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 circumstances, 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 quantity 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 circumstances 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 quantity 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 quantity 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 assume 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 glasses, 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 quantity 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. It is an acquired advantage only, which one artificer has over his neighbour, who exercises another trade; and yet they both find it more advantageous to buy of one another, than to make what does not belong to their particular trades.
Merchants and manufacturers are the people who derive the greatest advantage from this monopoly of the home market. The prohibition of the importation of foreign cattle and of salt provisions, together with the high duties upon foreign corn, which in times of moderate plenty amount to a prohibition, are not near so advantageous to the graziers and farmers of Great Britain, as other regulations of the same kind are to its merchants and manufacturers. Manufactures, those of the finer kind especially, are more easily transported from one country to another than corn or cattle. It is in the fetching and carrying manufactures, accordingly, that foreign trade is chiefly employed. In manufactures, a very small advantage will enable foreigners to undersell our own workmen, even in the home market. It will require a very great one to enable them to do so in the rude produce of the soil. If the free importation of foreign manufactures were permitted, several of the home manufactures would probably suffer, and some of them perhaps go to ruin altogether, and a considerable part of the stock and industry at present employed in them, would be forced to find out some other employment. But the freest importation of the rude produce of the soil could have no such effect upon the agriculture of the country.
If the importation of foreign cattle, for example, were made ever so free, so few could be imported, that the grazing trade of Great Britain could be little affected by it. Live cattle are, perhaps, the only commodity of which the transportation is more expensive by sea than by land. By land they carry themselves to market. By sea, not only the cattle, but their food and their water too, must be carried at no small expense and inconveniency. The short sea between Ireland and Great Britain, indeed, renders the importation of Irish cattle more easy. But though the free importation of them, which was lately permitted only for a limited time, were rendered perpetual, it could have no considerable effect upon the interest of the graziers of Great Britain. Those parts of Great Britain which border upon the Irish sea are all grazing countries. Irish cattle could never be imported for their use, but must be drove through those very extensive countries, at no small expense and inconveniency, before they could arrive at their proper market. Fat cattle could not be drove so far. Lean cattle, therefore, could only be imported; and such importation could interfere not with the interest of the feeding or fattening countries, to which, by reducing the price of lean cattle it would rather be advantageous, but with that of the breeding countries only. The small number of Irish cattle imported since their importation was permitted, together with the good price at which lean cattle still continue to sell, seem to demonstrate, that even the breeding countries of Great Britain are never likely to be much affected by the free importation of Irish cattle. The common people of Ireland, indeed, are said to have sometimes opposed with violence the exportation of their cattle. But if the exporters had found any great advantage in continuing the trade, they could easily, when the law was on their side, have conquered this mobbish opposition.
Feeding and fattening countries, besides, must always be highly improved, whereas breeding countries are generally uncultivated. The high price of lean cattle, by augmenting the value of uncultivated land, is like a bounty against improvement. To any country which was highly improved throughout, it would be more advantageous to import its lean cattle than to breed them. The province of Holland, accordingly, is said to follow this maxim at present. The mountains of Scotland, Wales, and Northumberland, indeed, are countries not capable of much improvement, and seem destined by nature to be the breeding countries of Great Britain. The freest importation of foreign cattle could have no other effect than to hinder those breeding countries from taking advantage of the increasing population and improvement of the rest of the kingdom, from raising their price to an exorbitant height, and from laying a real tax upon all the more improved and cultivated parts of the country.
The freest importation of salt provisions, in the same manner, could have as little effect upon the interest of the graziers of Great Britain as that of live cattle. Salt provisions are not only a very bulky commodity, but when compared with fresh meat they are a commodity both of worse quality, and, as they cost more labour and expense, of higher price. They could never, therefore, come into competition with the fresh meat, though they might with the salt provisions of the country. They might be used for victualling ships for distant voyages, and such like uses, but could never make any considerable part of the food of the people. The small quantity of salt provisions imported from Ireland since their importation was rendered free, is an experimental proof that our graziers have nothing to apprehend from it. It does not appear that the price of butcher's meat has ever been sensibly affected by it.
Even the free importation of foreign corn could very little affect the interest of the farmers of Great Britain. Corn is a much more bulky commodity than butcher's meat. A pound of wheat at a penny is as dear as a pound of butcher's meat at fourpence. The small quantity of foreign corn imported even in times of the greatest scarcity, may satisfy our farmers that they can have nothing to fear from the freest importation. The average quantity imported, one year with another, amounts only, according to the very well informed author of the Tracts upon the Corn Trade, to 23,728 quarters of all sorts of grain, and does not exceed the five hundredth and seventy-one part of the annual consumption. But as the bounty upon corn occasions a greater exportation in years of plenty, so it must, of consequence, occasion a greater importation in years of scarcity, than in the actual state of tillage would otherwise take place. By means of it, the plenty of one year does not compensate the scarcity of another; and as the average quantity exported is necessarily augmented by it, so must likewise, in the actual state of tillage, the average quantity imported. If there were no bounty, as less corn would be exported, suit is probable that, one year with another, less would be imported than at present. The corn-merchants, the fetchers and carriers of corn between Great Britain and foreign countries, would have much less employment, and might suffer considerably; but the country gentlemen and farmers could suffer very little. It is in the corn-merchants, accordingly, rather than the country gentlemen and farmers, that I have observed the greatest anxiety for the renewal and continuation of the bounty.
Country gentlemen and farmers are, to their great honour, of all people, the least subject to the wretched spirit of monopoly. The undertaker of a great manufactory is sometimes alarmed if another work of the same kind is established within twenty miles of him; the Dutch undertaker of the woollen manufacture at Abbeville, stipulated that no work of the same kind should be established within thirty leagues of that city. Farmers and country gentlemen, on the contrary, are generally disposed rather to promote, than to obstruct, the cultivation and improvement of their neighbours farms and estates. They have no secrets, such as those of the greater part of manufacturers, but are generally rather fond of communicating to their neighbours, and of extending as far as possible any new practice which they may have found to be advantageous. "Pius quaestus", says old Cato, "stabilissimusque, minimeque invidiosus; minimeque male cogitantes sunt, qui in eo studio occupati sunt." Country gentlemen and farmers, dispersed in different parts of the country, cannot so easily combine as merchants and manufacturers, who being collected into towns, and accustomed to that exclusive corporation spirit which prevails in them, naturally endeavour to obtain, against all their countrymen, the same exclusive privilege which they generally possess against the inhabitants of their respective towns. They accordingly seem to have been the original inventors of those restraints upon the importation of foreign goods, which secure to them the monopoly of the home market. It was probably in imitation of them, and to put themselves upon a level with those who, they found, were disposed to oppress them, that the country gentlemen and farmers of Great Britain so far forgot the generosity which is natural to their station, as to demand the exclusive privilege of supplying their countrymen with corn and butcher's meat. They did not, perhaps, take time to consider how much less their interest could be affected by the freedom of trade, than that of the people whose example they followed.
