The Wealth of Nations_ Books 4-5 - Adam Smith [65]
There is not, probably, between any two countries a trade which consists altogether in the exchange either of native commodities on both sides, or of native commodities on one side and of foreign goods on the other. Almost all countries exchange with one another partly native and partly foreign goods. That country, however, in whose cargoes there is the greatest proportion of native, and the least of foreign goods, will always be the principal gainer.
If it was not with tobacco and East India goods, but with gold and silver, that England paid for the commodities annually imported from France, the balance, in this case, would be supposed uneven, commodities not being paid for with commodities, but with gold and silver. The trade, however, would, in this case, as in the foregoing, give some revenue to the inhabitants of both countries, but more to those of France than to those of England. It would give some revenue to those of England. The capital which had been employed in producing the English goods that purchased this gold and silver, the capital which had been distributed among, and given revenue to, certain inhabitants of England, would thereby be replaced and enabled to continue that employment. The whole capital of England would no more be diminished by this exportation of gold and silver than by the exportation of an equal value of any other goods. On the contrary, it would in most cases be augmented. No goods are sent abroad but those for which the demand is supposed to be greater abroad than at home, and of which the returns consequently, it is expected, will be of more value at home than the commodities exported. If the tobacco which, in England, is worth only a hundred thousand pounds, when sent to France will purchase wine which is, in England, worth a hundred and ten thousand, this exchange will equally augment the capital of England by ten thousand pounds. If a hundred thousand pounds of English gold, in the same manner, purchase French wine which, in England, is worth a hundred and ten thousand, this exchange will equally augment the capital of England by ten thousand pounds. As a merchant who has a hundred and ten thousand pounds worth of wine in his cellar is a richer man than he who has only a hundred thousand pounds worth of tobacco in his warehouse, so is he likewise a richer man than he who has only a hundred thousand pounds worth of gold in his coffers. He can put into motion a greater quantity of industry, and give revenue, maintenance, and employment to a greater number of people than either of the other two. But the capital of the country is equal to the capitals of all its different inhabitants, and the quantity of industry
