is the acquisition of any new power of obtaining cheap commodities from foreign countries. If necessaries are cheapened, whether they are so by improvements at home or importation from abroad, is exactly the same thing to wages and profits. Unless the laborer obtains and, by an improvement of his habitual standard, keeps the whole benefit, the cost of labor is lowered and the rate of profit raised. As long as food can continue to be imported for an increasing population without any diminution of cheapness, so long the declension of profits through the increase of population and capital is arrested, and accumulation may go on without making the rate of profit draw nearer to the minimum. And on this ground it is believed by some that the repeal of the corn laws has opened to [England] a long era of rapid increase of capital with an undiminished rate of profit.
Before inquiring whether this expectation is reasonable, one remark must be made, which is much at variance with commonly received notions. Foreign trade does not necessarily increase the field of employment for capital. When foreign trade makes room for more capital at the same profit, it is by enabling the necessaries of life, or the habitual articles of the laborer's consumption, to be obtained at smaller cost. It may do this in two ways: by the importation either of those commodities themselves, or of the means and appliances for producing them. Cheap iron has, in a certain measure, the same effect on profits and the cost of [pg 508] labor as cheap corn, because cheap iron makes cheap tools for agriculture and cheap machinery for clothing. But a foreign trade, which neither directly nor by any indirect consequence increases the cheapness of anything consumed by the laborers, does not, any more than an invention or discovery in the
