Here, however, there enters another consideration. The manufacturer who calculates his cost of production and, in accordance with it, the price of the product, takes into account the wear and tear of the instruments of labor. If a machine costs him, for example, one thousand dollars, and this machine is used up in ten years, he adds one hundred dollars annually to the price of the commodities, in order to be able after ten years to replace the worn-out machine with a new one. In the same manner, the cost of production of simple labor-power must include the cost of propagation, by means of which the race of workers is enabled to multiply itself and to replace worn-out workers with new ones. The wear and tear of the worker, therefore, is calculated in the same manner as the wear and tear of the machine.
Thus, the cost of production of simple labor-power amounts to the cost of the existence and propagation of the worker. The price of this cost of existence and propagation constitutes wages. The wages thus deter- mined are called the minimum of wages. This minimum wage, like the determination of the price of commodities in general by cost of production, does not hold good for the single individual, but only for the race. Individual workers, indeed, millions of workers, do not receive enough to be able to exist and to propagate themselves; but the wages of the whole working class adjust themselves, within the limits of their fluctuations, to this minimum.
Now that we have come to an understanding in regard to the most general laws which govern wages, as well as the price of every other commodity, we can examine our subject more particularly.
