The Wealth of Nations_ Books 4-5 - Adam Smith [98]
Let us suppose, however, that the whole was on account of Great Britain, and that it amounted to a still greater sum than Mr Baretti seems to imagine; this trade would not, upon that account, be more advantageous than any other in which, for the same value sent out, we received an equal value of consumable goods in return.
It is but a very small part of this importation which, it can be supposed, is employed as an annual addition either to the plate or to the coin of the kingdom. The rest must all be sent abroad and exchanged for consumable goods of some kind or other. But if those consumable goods were purchased directly with the produce of English industry, it would be more for the advantage of England than first to purchase with that produce the gold of Portugal, and afterwards to purchase with that gold those consumable goods. A direct foreign trade of consumption is always more advantageous than a round-about one; and to bring the same value of foreign goods to the home market, requires a much smaller capital in the one way than in the other. If a smaller share of its industry, therefore, had been employed in producing goods fit for the Portugal market, and a greater in producing those fit for the other markets, where those consumable goods for which there is a demand in Great Britain are to be had, it would have been more for the advantage of England. To procure both the gold, which it wants for its own use, and the consumable goods, would, in this way, employ a much smaller capital than at present. There would be a spare capital, therefore, to be employed for other purposes, in exciting an additional quantity of industry, and in raising a greater annual produce.
Though Britain were entirely excluded from the Portugal trade, it could find very little difficulty in procuring all the annual supplies of gold which it wants, either for the purposes of plate, or of coin, or of foreign trade. Gold, like every other commodity, is always somewhere or another to be got for its value by those who have that value to give for it. The annual surplus of gold in Portugal, besides, would still be sent abroad, and though not carried away by Great Britain, would be carried away by some other nation, which would be glad to sell it again for its price, in the same manner as Great Britain does at present. In buying gold of Portugal, indeed, we buy it at the first hand; whereas, in buying it of any other nation, except Spain, we should buy it at the second, and might pay somewhat dearer. This difference, however, would surely be too insignificant to deserve the public attention.
Almost all our gold, it is said, comes from Portugal. With other nations the balance of trade is either against us, or not much in our favour. But we should remember that the more gold we import from one country, the less we must necessarily import from all others. The effectual demand for gold, like that for every other commodity, is in every country limited to a certain quantity. If nine-tenths of this quantity are imported from one country, there remains a tenth only to be imported from all others. The more gold besides that is annually imported from some particular countries, over and above what is requisite for plate and for coin, the more must necessarily be exported to some others; and the more that most insignificant object of modern policy, the balance of trade, appears to be in our favour with some particular countries, the more it must
