The Wealth of Nations_ Books 4-5 - Adam Smith [173]
This continual increase both of the rude and manufactured produce of those landed nations would in due time create a greater capital than could, with the ordinary rate of profit, be employed either in agriculture or in manufactures. The surplus of this capital would naturally turn itself to foreign trade, and be employed in exporting to foreign countries such parts of the rude and manufactured produce of its own country as exceeded the demand of the home market. In the exportation of the produce of their own country, the merchants of a landed nation would have an advantage of the same kind over those of mercantile nations which its artificers and manufacturers had over the artificers and manufacturers of such nations; the advantage of finding at home that cargo and those stores and provisions which the others were obliged to seek for at a distance. With inferior art and skill in navigation, therefore, they would be able to sell that cargo as cheap in foreign markets as the merchants of such mercantile nations; and with equal art and skill they would be able to sell it cheaper. They would soon, therefore, rival those mercantile nations in this branch of foreign trade, and in due time would jostle them out of it altogether.
According to this liberal and generous system, therefore, the most advantageous method in which a landed nation can raise up artificers, manufacturers, and merchants of its own is to grant the most perfect freedom of trade to the artificers, manufacturers, and merchants of all other nations. It thereby raises the value of the surplus produce of its own land, of which the continual increase gradually establishes a fund, which in due time necessarily raises up all the artificers, manufacturers, and merchants whom it has occasion for.
When a landed nation, on the contrary, oppresses either by high duties or by prohibitions the trade of foreign nations, it necessarily hurts its own interest in two different ways. First, by raising the price of all foreign goods and of all sorts of manufactures, it necessarily sinks the real value of the surplus produce of its own land, with which, or, what comes to the same thing, with the price of which it purchases those foreign goods and manufactures. Secondly, by giving a sort of monopoly of the home market to its own merchants, artificers, and manufacturers, it raises the rate of mercantile and manufacturing profit in proportion to that of agricultural profit, and consequently either draws from agriculture a part of the capital which had before been employed in it, or hinders from going to it a part of what would otherwise have gone to it. This policy, therefore, discourages agriculture in two different ways; first, by sinking the real value of its produce, and thereby lowering the rate of its profit; and, secondly, by raising the rate of profit in all other employments. Agriculture is rendered less advantageous, and trade and manufactures more advantageous than they otherwise would be; and every man is tempted by his own interest to turn, as much as he can, both his capital and his industry from the former to the latter employments.
Though, by this oppressive policy, a landed nation should be able to raise up artificers, manufacturers, and merchants of its own somewhat sooner than it could do by the freedom of trade– a matter, however, which is not a little doubtful – yet it would raise them up, if one may say so, prematurely, and before it was perfectly ripe for them. By raising up too hastily one species of industry, it would depress another more valuable species of industry. By raising up too hastily a species of industry which only replaces the stock which employs it, together with the ordinary profit, it would depress a species of industry which, over and above replacing that stock with its profit, affords likewise a net produce, a free rent to the landlord. It would depress productive labour, by encouraging too hastily that labour which
