Friedrich Engels quotes - page 2
Labor is a commodity, like any other, and its price is therefore determined by exactly the same laws that apply to other commodities. In a regime of big industry or of free competition – as we shall see, the two come to the same thing – the price of a commodity is, on the average, always equal to its cost of production. Hence, the price of labor is also equal to the cost of production of labor. But, the costs of production of labor consist of precisely the quantity of means of subsistence necessary to enable the worker to continue working, and to prevent the working class from dying out. The worker will therefore get no more for his labor than is necessary for this purpose; the price of labor, or the wage, will, in other words, be the lowest, the minimum, required for the maintenance of life.
