If we suppose him to buy the materials and tools instead of producing them, the case is not altered: he then repays to a previous producer the wages which that previous producer has paid. It is true he repays it to him with a profit; and, if he had produced the things himself, he himself must have had that profit on this part of his outlay [pg 226] as well as on every other part. The fact, however, remains, that in the whole process of production, beginning with the materials and tools and ending with the finished product, all the advances have consisted of nothing but wages, except that certain of the capitalists concerned have, for the sake of general convenience, had their share of profit paid to them before the operation was completed.
§ 5. The Rate of Profit depends on the Cost of Labor.
It thus appears that the two elements on which, and which alone, the gains of the capitalists depend, are, first, the magnitude of the produce, in other words, the productive power of labor; and secondly, the proportion of that produce obtained by the laborers themselves; the ratio which the remuneration of the laborers bears to the amount they produce.
We thus arrive at the conclusion of Ricardo and others, that the rate of profits depends upon wages; rising as wages fall, and falling as wages rise. In adopting, however, this doctrine, I must insist upon making a most necessary alteration in its wording. Instead of saying that profits depend on wages, let us say (what Ricardo really meant) that they depend on the cost of labor.
Wages and the cost of labor; what labor brings in to the laborer and what it costs to the capitalist are ideas quite distinct, and which it is of the utmost importance to keep so. For this purpose it is essential not to designate them, as is almost always done, by the same name. Wages, in public discussions, both oral and printed, being looked upon
