Note A2-5-7 — Chapter III

International trade makes imported commodities cheaper and exported commodities dearer, but the aggregate of consumers gain more in the former case than they lose in the latter, because they now enjoy the blessings of the international division of labor. But, even with this general enrichment, single classes of the people, and even the majority, may have to suffer; as, for instance, when in the exchange of corn against iron, the cheapening of the iron profits the people less than the consequent dearness of corn injures them. (Fawcett, Manual, 391.)
