It is perfectly true that if my neighbour in Threadneedle Street does succeed in selling £2000 worth of cutlery to the New Englander, there is another distinct national profit to England and to America. [Footnote: I am assuming for simplicity throughout that every exchange made by private merchants in this foreign trade is a successful speculation; if in any particular speculation a merchant loses, his country loses the same amount. As foreign trade, on the whole, is an enormous national profit, I am justified in sinking the particular cases of loss. It may be said, "But perhaps all your exchange of gold for wheat is a national loss": it is evident that when the trade takes this form the merchants who import foreign corn stop their operations instantly; in practice they stop them with prescient instinct.] But whether he succeeds in making a bargain or not, I object to being interfered with by Government, and prevented making my own little profit. If my neighbour is practically deprived of his profitable bargain by Government action on the part of the Americans--if they are Protectionists and believe that gold is the only National Wealth, and put a heavy duty on cutlery--if by doing this they prevent an exchange profitable to both nations--they stop TWO merchants from a profitable stroke of business. Whether they injure the English merchant or the Bostonian would-be purchaser of cutlery MOST is (as above explained) very difficult to prove in any well-ascertained instance, but it is quite certain that the interference of the American import duty causes a loss to each merchant and to each nation. Where now is Reciprocity and where Retaliation? We can no doubt say to the Americans, "As you have injured us in the matter of cutlery, so will we injure you by putting a duty on wheat." But it is merely cutting off one's nose to spite one's face. In the exchange of gold for wheat the division of the profit on one transaction is uncertain, but in the long run it is probably about equal between the English and the American merchants, i.e. between the English and the American nations. (I am not overlooking the fact that the ultimate benefit to England is cheap bread; but it is unnecessary in the present argument to follow the food down the throats of the consumers: the wheat is really worth to the corn merchants what they can get for it from the consumers.) We cannot stop the corn trade with America by a duty (or diminish it) without as great a loss to ourselves (probably a greater) than to them; the retaliation in putting a duty on corn because the Americans put a duty on cutlery would be (with our lights) mere spite: it would be as though a farmer who took one sample of wheat to market and one of barley, should meet a factor who offered him his price for the wheat, but would not spring to his price for the barley, and the farmer should thereupon sulkily carry both his samples home again.
