Chapter VII
The General Law that Determines the Rise and Fall of Wages and Profits
We have said: “Wages are not a share of the worker in the commodities produced by him. Wages are that part of already existing commodities with which the capitalist buys a certain amount of productive labor-power.” But the capitalist must replace these wages out of the price for which he sells the product made by the worker; he must so replace it that, as a rule, there remains to him a surplus above the cost of production expended by him, that is, he must get a profit. The selling price of the commodities produced by the worker is divided, from the point of view of the capitalist, into three parts: First, the replacement of the price of the raw materials advanced by him, in addition to the replacement of the wear and tear of the tools, machines, and other instruments of labor likewise advanced by him; second, the replacement of the wages advanced; and third, the surplus left over, i.e., the profit of the capitalist. While the first part merely replaces previously existing values, it is evident that the replacement of the wages and the surplus (the profit of capital) are as a whole taken out of the new value, which is produced by the labor of the worker and added to the raw materials. And in this sense we can view wages as well as profit, for the purpose of comparing them with each other, as shares in the product of the worker.
