The General Law that Determines the Rise and Fall of Wages and Profits: Wage Labour and Capital

by Karl Marx

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 leftover – i.e., the profit of the capitalist. Continue reading

The Nature and Growth of Capital: Wage Labour and Capital

by Karl Marx

Capital consists of raw materials, instruments of labour, and means of subsistence of all kinds, which are employed in producing new raw materials, new instruments, and new means of subsistence.

So say the economists.

What is a Negro slave? A man of the black race. The one explanation is worthy of the other.

Torn away from these conditions, it is as little capital as gold is itself money, or sugar is the price of sugar. Continue reading

By What Are Wages Determined?: Wage Labour and Capital

by Karl Marx

Now, the same general laws which regulate the price of commodities in general, naturally regulate wages, or the price of labour-power. Wages will now rise, now fall, according to the relation of supply and demand, according as competition shapes itself between the buyers of labour-power, the capitalists, and the sellers of labour-power, the workers. The fluctuations of wages correspond to the fluctuation in the price of commodities in general. But within the limits of these fluctuations the price of labour-power will be determined by the cost of production, by the labour-time necessary for production of this commodity: labour-power.

What, then, is the cost of production of labour-power? Continue reading
