Rh § 4.Before proceeding farther, let us contrast this view of the benefits of international commerce with other theories which have prevailed, and which to a certain extent still prevail, on the same subject.

According to the doctrine now stated, the only direct advantage of foreign commerce consists in the imports. A country obtains things which it either could not have produced at all, or which it must have produced at a greater expense of capital and labour than the cost of the things which it exports to pay for them. It thus obtains a more ample supply of the commodities it wants, for the same labour and capital; or the same supply, for less labour and capital, leaving the surplus disposable to produce other things. The vulgar theory disregards this benefit, and deems the advantage of commerce to reside in the exports: as if not what a country obtains, but what it parts with, by its foreign trade, was supposed to constitute the gain to it. An extended market for its produce—an abundant consumption for its goods—a vent for its surplus—are the phrases by which it has been customary to designate the uses and recommendations of commerce with foreign countries. This notion is intelligible, when we consider that the authors and leaders of opinion on mercantile questions have always hitherto been the selling class. It is in truth a surviving relic of the Mercantile Theory, according to which, money being the only wealth, selling, or in other words, exchanging goods for money, was (to countries without mines of their own) the only way of growing rich—and importation of goods, that is to say, parting with money, was so much subtracted from the benefit.

The notion that money alone is wealth, has been long defunct, but it has left many of its progeny behind it; and even its destroyer, Adam Smith, retained some opinions which it is impossible to trace to any other origin. Adam Smith's theory of the benefit of foreign trade, was that it afforded an outlet for the surplus produce of a country, and enabled
