of our own products. But, in the next place, a very short interval of paying in money would so lower prices as either to stop a part of the importation, or raise up a foreign demand for our produce, sufficient to pay for the imports. I grant that this disturbance of the equation of international demand would be in some degree to our disadvantage, in the purchase of other imported articles; and that a country which prohibits some foreign commodities, does, cæteris paribus, obtain those which it does not prohibit at a less price than it would otherwise have to pay. To express the same thing in other words: a country which destroys or prevents altogether certain branches of foreign trade, thereby annihilating a general gain to the world, which would be shared in some proportion between itself and other countries, does, in some circumstances, draw to itself, at the expense of foreigners, a larger share than would else belong to it of the gain arising from that portion of its foreign trade which it suffers to subsist. But even this it can only be enabled to do, if foreigners do not maintain equivalent prohibitions or restrictions against its commodities. In any case, the justice or expediency of destroying one of two gains, in order to engross a rather larger share of the other, does not require much discussion; the gain, too, which is destroyed, being, in proportion to the magnitude of the transactions, the larger of the two, since it is the one which capital, left to itself, is supposed to seek by preference.
§ 3. —supported by pleas of national subsistence and national defense.
Defeated as a general theory, the Protectionist doctrine finds support in some particular cases from considerations which, when really in point, involve greater interests than mere saving of labor—the interests of national subsistence and of national defense.359 The discussions on the Corn [pg 610] Laws have familiarized everybody with the plea that we ought to be independent of foreigners
