In seeking for employment to a capital, manufactures are, upon equal or nearly equal profits, naturally preferred to foreign commerce, for the same reason that agriculture is naturally preferred to manufactures. As the capital of the landlord or farmer is more secure than that of the manufacturer, so the capital of the manufacturer, being at all times more within his view and command, is more secure than that of the foreign merchant. In every period, indeed, of every society, the surplus part both of the rude and manufactured produce, or that for which there is no demand at home, must be sent abroad in order to be exchanged for something for which there is some demand at home. But whether the capital, which carries this surplus produce abroad, be a foreign or a domestic one is of very little importance. If the society has not acquired sufficient capital both to cultivate all its lands, and to manufacture in the completest manner the whole of its rude produce, there is even a considerable advantage that rude produce should be exported by a foreign capital, in order that the whole stock of the society may be employed in more useful purposes. The wealth of ancient Egypt, that of China and Indostan, sufficiently demonstrate that a nation may attain a very high degree of opulence though the greater part of its exportation trade be carried on by foreigners. The progress of our North American and West Indian colonies would have been much less rapid had no capital but what belonged to themselves been employed in exporting their surplus produce.
