An Inquiry into the Nature and Causes of the Wealth of Nations Part 24

It is not always necessary to acc.u.mulate gold and silver, in order to enable a country to carry on foreign wars, and to maintain fleets and armies in distant countries. Fleets and armies are maintained, not with gold and silver, but with consumable goods. The nation which, from the annual produce of its domestic industry, from the annual revenue arising out of its lands, and labour, and consumable stock, has wherewithal to purchase those consumable goods in distant countries, can maintain foreign wars there.

A nation may purchase the pay and provisions of an army in a distant country three different ways; by sending abroad either, first, some part of its acc.u.mulated gold and silver; or, secondly, some part of the annual produce of its manufactures; or, last of all, some part of its annual rude produce.

The gold and silver which can properly be considered as acc.u.mulated, or stored up in any country, may be distinguished into three parts; first, the circulating money; secondly, the plate of private families; and, last of all, the money which may have been collected by many years parsimony, and laid up in the treasury of the prince.

It can seldom happen that much can be spared from the circulating money of the country; because in that there can seldom be much redundancy.

The value of goods annually bought and sold in any country requires a certain quant.i.ty of money to circulate and distribute them to their proper consumers, and can give employment to no more. The channel of circulation necessarily draws to itself a sum sufficient to fill it, and never admits any more. Something, however, is generally withdrawn from this channel in the case of foreign war. By the great number of people who are maintained abroad, fewer are maintained at home. Fewer goods are circulated there, and less money becomes necessary to circulate them. An extraordinary quant.i.ty of paper money of some sort or other, too, such as exchequer notes, navy bills, and bank bills, in England, is generally issued upon such occasions, and, by supplying the place of circulating gold and silver, gives an opportunity of sending a greater quant.i.ty of it abroad. All this, however, could afford but a poor resource for maintaining a foreign war, of great expense, and several years duration.

The melting down of the plate of private families has, upon every occasion, been found a still more insignificant one. The French, in the beginning of the last war, did not derive so much advantage from this expedient as to compensate the loss of the fas.h.i.+on.

The acc.u.mulated treasures of the prince have in former times afforded a much greater and more lasting resource. In the present times, if you except the king of Prussia, to acc.u.mulate treasure seems to be no part of the policy of European princes.

The funds which maintained the foreign wars of the present century, the most expensive perhaps which history records, seem to have had little dependency upon the exportation either of the circulating money, or of the plate of private families, or of the treasure of the prince. The last French war cost Great Britain upwards of 90,000,000, including not only the 75,000,000 of new debt that was contracted, but the additional 2s. in the pound land-tax, and what was annually borrowed of the sinking fund. More than two-thirds of this expense were laid out in distant countries; in Germany, Portugal, America, in the ports of the Mediterranean, in the East and West Indies. The kings of England had no acc.u.mulated treasure. We never heard of any extraordinary quant.i.ty of plate being melted down. The circulating gold and silver of the country had not been supposed to exceed 18,000,000. Since the late recoinage of the gold, however, it is believed to have been a good deal under-rated.

Let us suppose, therefore, according to the most exaggerated computation which I remember to have either seen or heard of, that, gold and silver together, it amounted to 30,000,000. Had the war been carried on by means of our money, the whole of it must, even according to this computation, have been sent out and returned again, at least twice in a period of between six and seven years. Should this be supposed, it would afford the most decisive argument, to demonstrate how unnecessary it is for government to watch over the preservation of money, since, upon this supposition, the whole money of the country must have gone from it, and returned to it again, two different times in so short a period, without any body's knowing any thing of the matter. The channel of circulation, however, never appeared more empty than usual during any part of this period. Few people wanted money who had wherewithal to pay for it. The profits of foreign trade, indeed, were greater than usual during the whole war, but especially towards the end of it. This occasioned, what it always occasions, a general over-trading in all the ports of Great Britain; and this again occasioned the usual complaint of the scarcity of money, which always follows over-trading. Many people wanted it, who had neither wherewithal to buy it, nor credit to borrow it; and because the debtors found it difficult to borrow, the creditors found it difficult to get payment. Gold and silver, however, were generally to be had for their value, by those who had that value to give for them.

The enormous expense of the late war, therefore, must have been chiefly defrayed, not by the exportation of gold and silver, but by that of British commodities of some kind or other. When the government, or those who acted under them, contracted with a merchant for a remittance to some foreign country, he would naturally endeavour to pay his foreign correspondent, upon whom he granted a bill, by sending abroad rather commodities than gold and silver. If the commodities of Great Britain were not in demand in that country, he would endeavour to send them to some other country in which he could purchase a bill upon that country.

The transportation of commodities, when properly suited to the market, is always attended with a considerable profit; whereas that of gold and silver is scarce ever attended with any. When those metals are sent abroad in order to purchase foreign commodities, the merchant's profit arises, not from the purchase, but from the sale of the returns. But when they are sent abroad merely to pay a debt, he gets no returns, and consequently no profit. He naturally, therefore, exerts his invention to find out a way of paying his foreign debts, rather by the exportation of commodities, than by that of gold and silver. The great quant.i.ty of British goods, exported during the course of the late war, without bringing back any returns, is accordingly remarked by the author of the Present State of the Nation.

Besides the three sorts of gold and silver above mentioned, there is in all great commercial countries a good deal of bullion alternately imported and exported, for the purposes of foreign trade. This bullion, as it circulates among different commercial countries, in the same manner as the national coin circulates in every country, may be considered as the money of the great mercantile republic. The national coin receives its movement and direction from the commodities circulated within the precincts of each particular country; the money in the mercantile republic, from those circulated between different countries.

Both are employed in facilitating exchanges, the one between different individuals of the same, the other between those of different nations.

Part of this money of the great mercantile republic may have been, and probably was, employed in carrying on the late war. In time of a general war, it is natural to suppose that a movement and direction should be impressed upon it, different from what it usually follows in profound peace, that it should circulate more about the seat of the war, and be more employed in purchasing there, and in the neighbouring countries, the pay and provisions of the different armies. But whatever part of this money of the mercantile republic Great Britain may have annually employed in this manner, it must have been annually purchased, either with British commodities, or with something else that had been purchased with them; which still brings us back to commodities, to the annual produce of the land and labour of the country, as the ultimate resources which enabled us to carry on the war. It is natural, indeed, to suppose, that so great an annual expense must have been defrayed from a great annual produce. The expense of 1761, for example, amounted to more than 19,000,000. No acc.u.mulation could have supported so great an annual profusion. There is no annual produce, even of gold and silver, which could have supported it. The whole gold and silver annually imported into both Spain and Portugal, according to the best accounts, does not commonly much exceed 6,000,000 sterling, which, in some years, would scarce have paid four months expense of the late war.

The commodities most proper for being transported to distant countries, in order to purchase there either the pay and provisions of an army, or some part of the money of the mercantile republic to be employed in purchasing them, seem to be the finer and more improved manufactures; such as contain a great value in a small bulk, and can therefore be exported to a great distance at little expense. A country whose industry produces a great annual surplus of such manufactures, which are usually exported to foreign countries, may carry on for many years a very expensive foreign war, without either exporting any considerable quant.i.ty of gold and silver, or even having any such quant.i.ty to export.

A considerable part of the annual surplus of its manufactures must, indeed, in this case, be exported without bringing back any returns to the country, though it does to the merchant; the government purchasing of the merchant his bills upon foreign countries, in order to purchase there the pay and provisions of an army. Some part of this surplus, however, may still continue to bring back a return. The manufacturers during; the war will have a double demand upon them, and be called upon first to work up goods to be sent abroad, for paying the bills drawn upon foreign countries for the pay and provisions of the army: and, secondly, to work up such as are necessary for purchasing the common returns that had usually been consumed in the country. In the midst of the most destructive foreign war, therefore, the greater part of manufactures may frequently flourish greatly; and, on the contrary, they may decline on the return of peace. They may flourish amidst the ruin of their country, and begin to decay upon the return of its prosperity. The different state of many different branches of the British manufactures during the late war, and for some time after the peace, may serve as an ill.u.s.tration of what has been just now said.

No foreign war, of great expense or duration, could conveniently be carried on by the exportation of the rude produce of the soil. The expense of sending such a quant.i.ty of it into a foreign country as might purchase the pay and provisions of an army would be too great. Few countries, too, produce much more rude produce than what is sufficient for the subsistence of their own inhabitants. To send abroad any great quant.i.ty of it, therefore, would be to send abroad a part of the necessary subsistence of the people. It is otherwise with the exportation of manufactures. The maintenance of the people employed in them is kept at home, and only the surplus part of their work is exported. Mr Hume frequently takes notice of the inability of the ancient kings of England to carry on, without interruption, any foreign war of long duration. The English in those days had nothing wherewithal to purchase the pay and provisions of their armies in foreign countries, but either the rude produce of the soil, of which no considerable part could be spared from the home consumption, or a few manufactures of the coa.r.s.est kind, of which, as well as of the rude produce, the transportation was too expensive. This inability did not arise from the want of money, but of the finer and more improved manufactures. Buying and selling was transacted by means of money in England then as well as now. The quant.i.ty of circulating money must have borne the same proportion, to the number and value of purchases and sales usually transacted at that time, which it does to those transacted at present; or, rather, it must have borne a greater proportion, because there was then no paper, which now occupies a great part of the employment of gold and silver. Among nations to whom commerce and manufactures are little known, the sovereign, upon extraordinary occasions, can seldom draw any considerable aid from his subjects, for reasons which shall be explained hereafter. It is in such countries, therefore, that he generally endeavours to acc.u.mulate a treasure, as the only resource against such emergencies. Independent of this necessity, he is, in such a situation, naturally disposed to the parsimony requisite for acc.u.mulation. In that simple state, the expense even of a sovereign is not directed by the vanity which delights in the gaudy finery of a court, but is employed in bounty to his tenants, and hospitality to his retainers. But bounty and hospitality very seldom lead to extravagance; though vanity almost always does. Every Tartar chief, accordingly, has a treasure. The treasures of Mazepa, chief of the Cossacks in the Ukraine, the famous ally of Charles XII., are said to have been very great. The French kings of the Merovingian race had all treasures. When they divided their kingdom among their different children, they divided their treasures too. The Saxon princes, and the first kings after the Conquest, seem likewise to have acc.u.mulated treasures. The first exploit of every new reign was commonly to seize the treasure of the preceding king, as the most essential measure for securing the succession. The sovereigns of improved and commercial countries are not under the same necessity of acc.u.mulating treasures, because they can generally draw from their subjects extraordinary aids upon extraordinary occasions. They are likewise less disposed to do so. They naturally, perhaps necessarily, follow the mode of the times; and their expense comes to be regulated by the same extravagant vanity which directs that of all the other great proprietors in their dominions. The insignificant pageantry of their court becomes every day more brilliant; and the expense of it not only prevents acc.u.mulation, but frequently encroaches upon the funds destined for more necessary expenses. What Dercyllidas said of the court of Persia, may be applied to that of several European princes, that he saw there much splendour, but little strength, and many servants, but few soldiers.

The importation of gold and silver is not the princ.i.p.al, much less the sole benefit, which a nation derives from its foreign trade. Between whatever places foreign trade is carried on, they all of them derive two distinct benefits from it. It carries out that surplus part of the produce of their land and labour for which there is no demand among them, and brings back in return for it something else for which there is a demand. It gives a value to their superfluities, by exchanging them for something else, which may satisfy a part of their wants and increase their enjoyments. By means of it, the narrowness of the home market does not hinder the division of labour in any particular branch of art or manufacture from being carried to the highest perfection. By opening a more extensive market for whatever part of the produce of their labour may exceed the home consumption, it encourages them to improve its productive power, and to augment its annual produce to the utmost, and thereby to increase the real revenue and wealth of the society. These great and important services foreign trade is continually occupied in performing to all the different countries between which it is carried on. They all derive great benefit from it, though that in which the merchant resides generally derives the greatest, as he is generally more employed in supplying the wants, and carrying out the superfluities of his own, than of any other particular country. To import the gold and silver which may be wanted into the countries which have no mines, is, no doubt a part of the business of foreign commerce. It is, however, a most insignificant part of it. A country which carried on foreign trade merely upon this account, could scarce have occasion to freight a s.h.i.+p in a century.

It is not by the importation of gold and silver that the discovery of America has enriched Europe. By the abundance of the American mines, those metals have become cheaper. A service of plate can now be purchased for about a third part of the corn, or a third part of the labour, which it would have cost in the fifteenth century. With the same annual expense of labour and commodities, Europe can annually purchase about three times the quant.i.ty of plate which it could have purchased at that time. But when a commodity comes to be sold for a third part of what bad been its usual price, not only those who purchased it before can purchase three times their former quant.i.ty, but it is brought down to the level of a much greater number of purchasers, perhaps to more than ten, perhaps to more than twenty times the former number. So that there may be in Europe at present, not only more than three times, but more than twenty or thirty times the quant.i.ty of plate which would have been in it, even in its present state of improvement, had the discovery of the American mines never been made. So far Europe has, no doubt, gained a real conveniency, though surely a very trifling one. The cheapness of gold and silver renders those metals rather less fit for the purposes of money than they were before. In order to make the same purchases, we must load ourselves with a greater quant.i.ty of them, and carry about a s.h.i.+lling in our pocket, where a groat would have done before. It is difficult to say which is most trifling, this inconveniency, or the opposite conveniency. Neither the one nor the other could have made any very essential change in the state of Europe.

The discovery of America, however, certainly made a most essential one.

By opening a new and inexhaustible market to all the commodities of Europe, it gave occasion to new divisions of labour and improvements of art, which in the narrow circle of the ancient commerce could never have taken place, for want of a market to take off the greater part of their produce. The productive powers of labour were improved, and its produce increased in all the different countries of Europe, and together with it the real revenue and wealth of the inhabitants. The commodities of Europe were almost all new to America, and many of those of America were new to Europe. A new set of exchanges, therefore, began to take place, which had never been thought of before, and which should naturally have proved as advantageous to the new, as it certainly did to the old continent. The savage injustice of the Europeans rendered an event, which ought to have been beneficial to all, ruinous and destructive to several of those unfortunate countries.

The discovery of a pa.s.sage to the East Indies by the Cape of Good Hope, which happened much about the same time, opened perhaps a still more extensive range to foreign commerce, than even that of America, notwithstanding the greater distance. There were but two nations in America, in any respect, superior to the savages, and these were destroyed almost as soon as discovered. The rest were mere savages. But the empires of China, Indostan, j.a.pan, as well as several others in the East Indies, without having richer mines of gold or silver, were, in every other respect, much richer, better cultivated, and more advanced in all arts and manufactures, than either Mexico or Peru, even though we should credit, what plainly deserves no credit, the exaggerated accounts of the Spanish writers concerning the ancient state of those empires.

But rich and civilized nations can always exchange to a much greater value with one another, than with savages and barbarians. Europe, however, has. .h.i.therto derived much less advantage from its commerce with the East Indies, than from that with America. The Portuguese monopolized the East India trade to themselves for about a century; and it was only indirectly, and through them, that the other nations of Europe could either send out or receive any goods from that country. When the Dutch, in the beginning of the last century, began to encroach upon them, they vested their whole East India commerce in an exclusive company. The English, French, Swedes, and Danes, have all followed their example; so that no great nation of Europe has ever yet had the benefit of a free commerce to the East Indies. No other reason need be a.s.signed why it has never been so advantageous as the trade to America, which, between almost every nation of Europe and its own colonies, is free to all its subjects. The exclusive privileges of those East India companies, their great riches, the great favour and protection which these have procured them from their respective governments, have excited much envy against them. This envy has frequently represented their trade as altogether pernicious, on account of the great quant.i.ties of silver which it every year exports from the countries from which it is carried on. The parties concerned have replied, that their trade by this continual exportation of silver, might indeed tend to impoverish Europe in general, but not the particular country from which it was carried on; because, by the exportation of a part of the returns to other European countries, it annually brought home a much greater quant.i.ty of that metal than it carried out. Both the objection and the reply are founded in the popular notion which I have been just now examining. It is therefore unnecessary to say any thing further about either. By the annual exportation of silver to the East Indies, plate is probably somewhat dearer in Europe than it otherwise might have been; and coined silver probably purchases a larger quant.i.ty both of labour and commodities. The former of these two effects is a very small loss, the latter a very small advantage; both too insignificant to deserve any part of the public attention.

The trade to the East Indies, by opening a market to the commodities of Europe, or, what comes nearly to the same thing, to the gold and silver which is purchased with those commodities, must necessarily tend to increase the annual production of European commodities, and consequently the real wealth and revenue of Europe. That it has. .h.i.therto increased them so little, is probably owing to the restraints which it everywhere labours under.

I thought it necessary, though at the hazard of being tedious, to examine at full length this popular notion, that wealth consists in money or in gold and silver. Money, in common language, as I have already observed, frequently signifies wealth; and this ambiguity of expression has rendered this popular notion so familiar to us, that even they who are convinced of its absurdity, are very apt to forget their own principles, and, in the course of their reasonings, to take it for granted as a certain and undeniable truth. Some of the best English writers upon commerce set out with observing, that the wealth of a country consists, not in its gold and silver only, but in its lands, houses, and consumable goods of all different kinds. In the course of their reasonings, however, the lands, houses, and consumable goods, seem to slip out of their memory; and the strain of their argument frequently supposes that all wealth consists in gold and silver, and that to multiply those metals is the great object of national industry and commerce.

The two principles being established, however, that wealth consisted in gold and silver, and that those metals could be brought into a country which had no mines, only by the balance of trade, or by exporting to a greater value than it imported; it necessarily became the great object of political economy to diminish as much as possible the importation of foreign goods for home consumption, and to increase as much as possible the exportation of the produce of domestic industry. Its two great engines for enriching the country, therefore, were restraints upon importation, and encouragement to exportation.

The restraints upon importation were of two kinds.

First, restraints upon the importation of such foreign goods for home consumption as could be produced at home, from whatever country they were imported.

Secondly, restraints upon the importation of goods of almost all kinds, from those particular countries with which the balance of trade was supposed to be disadvantageous.

Those different restraints consisted sometimes in high duties, and sometimes in absolute prohibitions.

Exportation was encouraged sometimes by drawbacks, sometimes by bounties, sometimes by advantageous treaties of commerce with foreign states, and sometimes by the establishment of colonies in distant countries.

Drawbacks were given upon two different occasions. When the home manufactures were subject to any duty or excise, either the whole or a part of it was frequently drawn back upon their exportation; and when foreign goods liable to a duty were imported, in order to be exported again, either the whole or a part of this duty was sometimes given back upon such exportation.

Bounties were given for the encouragement, either of some beginning manufactures, or of such sorts of industry of other kinds as were supposed to deserve particular favour.

By advantageous treaties of commerce, particular privileges were procured in some foreign state for the goods and merchants of the country, beyond what were granted to those of other countries.

By the establishment of colonies in distant countries, not only particular privileges, but a monopoly was frequently procured for the goods and merchants of the country which established them.

The two sorts of restraints upon importation above mentioned, together with these four encouragements to exportation, const.i.tute the six princ.i.p.al means by which the commercial system proposes to increase the quant.i.ty of gold and silver in any country, by turning the balance of trade in its favour. I shall consider each of them in a particular chapter, and, without taking much farther notice of their supposed tendency to bring money into the country, I shall examine chiefly what are likely to be the effects of each of them upon the annual produce of its industry. According as they tend either to increase or diminish the value of this annual produce, they must evidently tend either to increase or diminish the real wealth and revenue of the country.

CHAPTER II. OF RESTRAINTS UPON IMPORTATION FROM FOREIGN COUNTRIES OF SUCH GOODS AS CAN BE PRODUCED AT HOME.

By restraining, either by high duties, or by absolute prohibitions, the importation of such goods from foreign countries as can be produced at home, the monopoly of the home market is more or less secured to the domestic industry employed in producing them. Thus the prohibition of importing either live cattle or salt provisions from foreign countries, secures to the graziers of Great Britain the monopoly of the home market for butcher's meat. The high duties upon the importation of corn, which, in times of moderate plenty, amount to a prohibition, give a like advantage to the growers of that commodity. The prohibition of the importation of foreign woollen is equally favourable to the woollen manufacturers. The silk manufacture, though altogether employed upon foreign materials, has lately obtained the same advantage. The linen manufacture has not yet obtained it, but is making great strides towards it. Many other sorts of manufactures have, in the same manner obtained in Great Britain, either altogether, or very nearly, a monopoly against their countrymen. The variety of goods, of which the importation into Great Britain is prohibited, either absolutely, or under certain circ.u.mstances, greatly exceeds what can easily be suspected by those who are not well acquainted with the laws of the customs.

That this monopoly of the home market frequently gives great encouragement to that particular species of industry which enjoys it, and frequently turns towards that employment a greater share of both the labour and stock of the society than would otherwise have gone to it, cannot be doubted. But whether it tends either to increase the general industry of the society, or to give it the most advantageous direction, is not, perhaps, altogether so evident.

The general industry of the society can never exceed what the capital of the society can employ. As the number of workmen that can be kept in employment by any particular person must bear a certain proportion to his capital, so the number of those that can be continually employed by all the members of a great society must bear a certain proportion to the whole capital of the society, and never can exceed that proportion.

No regulation of commerce can increase the quant.i.ty of industry in any society beyond what its capital can maintain. It can only divert a part of it into a direction into which it might not otherwise have gone; and it is by no means certain that this artificial direction is likely to be more advantageous to the society, than that into which it would have gone of its own accord.

Every individual is continually exerting himself to find out the most advantageous employment for whatever capital he can command. It is his own advantage, indeed, and not that of the society, which he has in view. But the study of his own advantage naturally, or rather necessarily, leads him to prefer that employment which is most advantageous to the society.

First, every individual endeavours to employ his capital as near home as he can, and consequently as much as he can in the support of domestic industry, provided always that he can thereby obtain the ordinary, or not a great deal less than the ordinary profits of stock.

Thus, upon equal, or nearly equal profits, every wholesale merchant naturally prefers the home trade to the foreign trade of consumption, and the foreign trade of consumption to the carrying trade. In the home trade, his capital is never so long out of his sight as it frequently is in the foreign trade of consumption. He can know better the character and situation of the persons whom he trusts; and if he should happen to be deceived, he knows better the laws of the country from which he must seek redress. In the carrying trade, the capital of the merchant is, as it were, divided between two foreign countries, and no part of it is ever necessarily brought home, or placed under his own immediate view and command. The capital which an Amsterdam merchant employs in carrying corn from Koningsberg to Lisbon, and fruit and wine from Lisbon to Koningsberg, must generally be the one half of it at Koningsberg, and the other half at Lisbon. No part of it need ever come to Amsterdam. The natural residence of such a merchant should either be at Koningsberg or Lisbon; and it can only be some very particular circ.u.mstances which can make him prefer the residence of Amsterdam. The uneasiness, however, which he feels at being separated so far from his capital, generally determines him to bring part both of the Koningsberg goods which he destines for the market of Lisbon, and of the Lisbon goods which he destines for that of Koningsberg, to Amsterdam; and though this necessarily subjects him to a double charge of loading and unloading as well as to the payment of some duties and customs, yet, for the sake of having some part of his capital always under his own view and command, he willingly submits to this extraordinary charge; and it is in this manner that every country which has any considerable share of the carrying trade, becomes always the emporium, or general market, for the goods of all the different countries whose trade it carries on. The merchant, in order to save a second loading and unloading, endeavours always to sell in the home market, as much of the goods of all those different countries as he can; and thus, so far as he can, to convert his carrying trade into a foreign trade of consumption. A merchant, in the same manner, who is engaged in the foreign trade of consumption, when he collects goods for foreign markets, will always be glad, upon equal or nearly equal profits, to sell as great a part of them at home as he can. He saves himself the risk and trouble of exportation, when, so far as he can, he thus converts his foreign trade of consumption into a home trade. Home is in this manner the centre, if I may say so, round which the capitals of the inhabitants of every country are continually circulating, and towards which they are always tending, though, by particular causes, they may sometimes be driven off and repelled from it towards more distant employments. But a capital employed in the home trade, it has already been shown, necessarily puts into motion a greater quant.i.ty of domestic industry, and gives revenue and employment to a greater number of the inhabitants of the country, than an equal capital employed in the foreign trade of consumption; and one employed in the foreign trade of consumption has the same advantage over an equal capital employed in the carrying trade. Upon equal, or only nearly equal profits, therefore, every individual naturally inclines to employ his capital in the manner in which it is likely to afford the greatest support to domestic industry, and to give revenue and employment to the greatest number of people of his own country.

Secondly, every individual who employs his capital in the support of domestic industry, necessarily endeavours so to direct that industry, that its produce may be of the greatest possible value.

The produce of industry is what it adds to the subject or materials upon which it is employed. In proportion as the value of this produce is great or small, so will likewise be the profits of the employer. But it is only for the sake of profit that any man employs a capital in the support of industry; and he will always, therefore, endeavour to employ it in the support of that industry of which the produce is likely to be of the greatest value, or to exchange for the greatest quant.i.ty either of money or of other goods.

But the annual revenue of every society is always precisely equal to the exchangeable value of the whole annual produce of its industry, or rather is precisely the same thing with that exchangeable value.

As every individual, therefore, endeavours as much as he can, both to employ his capital in the support of domestic industry, and so to direct that industry that its produce maybe of the greatest value; every individual necessarily labours to render the annual revenue of the society as great as he can. He generally, indeed, neither intends to promote the public interest, nor knows how much he is promoting it.

By preferring the support of domestic to that of foreign industry, he intends only his own security; and by directing that industry in such a manner as its produce may be of the greatest value, he intends only his own gain; and he is in this, as in many other cases, led by an invisible hand to promote an end which was no part of his intention. Nor is it always the worse for the society that it was no part of it. By pursuing his own interest, he frequently promotes that of the society more effectually than when he really intends to promote it. I have never known much good done by those who affected to trade for the public good.

It is an affectation, indeed, not very common among merchants, and very few words need be employed in dissuading them from it.

What is the species of domestic industry which his capital can employ, and of which the produce is likely to be of the greatest value, every individual, it is evident, can in his local situation judge much better than any statesman or lawgiver can do for him. The statesman, who should attempt to direct private people in what manner they ought to employ their capitals, would not only load himself with a most unnecessary attention, but a.s.sume an authority which could safely be trusted, not only to no single person, but to no council or senate whatever, and which would nowhere be so dangerous as in the hands of a man who had folly and presumption enough to fancy himself fit to exercise it.

To give the monopoly of the home market to the produce of domestic industry, in any particular art or manufacture, is in some measure to direct private people in what manner they ought to employ their capitals, and must in almost all cases be either a useless or a hurtful regulation. If the produce of domestic can be brought there as cheap as that of foreign industry, the regulation is evidently useless. If it cannot, it must generally be hurtful. It is the maxim of every prudent master of a family, never to attempt to make at home what it will cost him more to make than to buy. The tailor does not attempt to make his own shoes, but buys them of the shoemaker. The shoemaker does not attempt to make his own clothes, but employs a tailor. The farmer attempts to make neither the one nor the other, but employs those different artificers. All of them find it for their interest to employ their whole industry in a way in which they have some advantage over their neighbours, and to purchase with a part of its produce, or, what is the same thing, with the price of a part of it, whatever else they have occasion for.

What is prudence in the conduct of every private family, can scarce be folly in that of a great kingdom. If a foreign country can supply us with a commodity cheaper than we ourselves can make it, better buy it of them with some part of the produce of our own industry, employed in a way in which we have some advantage. The general industry of the country being always in proportion to the capital which employs it, will not thereby be diminished, no more than that of the abovementioned artificers; but only left to find out the way in which it can be employed with the greatest advantage. It is certainly not employed to the greatest advantage, when it is thus directed towards an object which it can buy cheaper than it can make. The value of its annual produce is certainly more or less diminished, when it is thus turned away from producing commodities evidently of more value than the commodity which it is directed to produce. According to the supposition, that commodity could be purchased from foreign countries cheaper than it can be made at home; it could therefore have been purchased with a part only of the commodities, or, what is the same thing, with a part only of the price of the commodities, which the industry employed by an equal capital would have produced at home, had it been left to follow its natural course. The industry of the country, therefore, is thus turned away from a more to a less advantageous employment; and the exchangeable value of its annual produce, instead of being increased, according to the intention of the lawgiver, must necessarily be diminished by every such regulation.

By means of such regulations, indeed, a particular manufacture may sometimes be acquired sooner than it could have been otherwise, and after a certain time may be made at home as cheap, or cheaper, than in the foreign country. But though the industry of the society may be thus carried with advantage into a particular channel sooner than it could have been otherwise, it will by no means follow that the sum-total, either of its industry, or of its revenue, can ever be augmented by any such regulation. The industry of the society can augment only in proportion as its capital augments, and its capital can augment only in proportion to what can be gradually saved out of its revenue. But the immediate effect of every such regulation is to diminish its revenue; and what diminishes its revenue is certainly not very likely to augment its capital faster than it would have augmented of its own accord, had both capital and industry been left to find out their natural employments.

Though, for want of such regulations, the society should never acquire the proposed manufacture, it would not upon that account necessarily be the poorer in anyone period of its duration. In every period of its duration its whole capital and industry might still have been employed, though upon different objects, in the manner that was most advantageous at the time. In every period its revenue might have been the greatest which its capital could afford, and both capital and revenue might have been augmented with the greatest possible rapidity.

The natural advantages which one country has over another, in producing particular commodities, are sometimes so great, that it is acknowledged by all the world to be in vain to struggle with them. By means of gla.s.ses, hot-beds, and hot-walls, very good grapes can be raised in Scotland, and very good wine, too, can be made of them, at about thirty times the expense for which at least equally good can be brought from foreign countries. Would it be a reasonable law to prohibit the importation of all foreign wines, merely to encourage the making of claret and Burgundy in Scotland? But if there would be a manifest absurdity in turning towards any employment thirty times more of the capital and industry of the country than would be necessary to purchase from foreign countries an equal quant.i.ty of the commodities wanted, there must be an absurdity, though not altogether so glaring, yet exactly of the same kind, in turning towards any such employment a thirtieth, or even a three hundredth part more of either. Whether the advantages which one country has over another be natural or acquired, is in this respect of no consequence. As long as the one country has those advantages, and the other wants them, it will always be more advantageous for the latter rather to buy of the former than to make.
