time evident that the interest of the consumer is to buy foreign commodities in preference to domestic whenever they are either cheaper or better, the interest of the consumer appeared in this respect to be contrary to the public interest; he was certain, if left to his own inclinations, to do what according to the theory was injurious to the public.
It was shown, however, in our analysis of the effects of international trade, as it had been often shown by former [pg 606] writers, that the importation of foreign commodities, in the common course of traffic, never takes place except when it is, economically speaking, a national good, by causing the same amount of commodities to be obtained at a smaller cost of labor and capital to the country. To prohibit, therefore, this importation, or impose duties which prevent it, is to render the labor and capital of the country less efficient in production than they would otherwise be, and compel a waste of the difference between the labor and capital necessary for the home production of the commodity and that which is required for producing the things with which it can be purchased from abroad. The amount of national loss thus occasioned is measured by the excess of the price at which the commodity is produced over that at which it could be imported. In the case of manufactured goods the whole difference between the two prices is absorbed in indemnifying the producers for waste of labor, or of the capital which supports that labor. Those who are supposed to be benefited, namely, the makers of the protected articles (unless they form an exclusive company, and have a monopoly against their own countrymen as well as against foreigners), do not obtain higher profits than other people. All is sheer loss to the country as well as to the consumer.
