“Owing to the extensive use of machinery and to division of
labour, the work of the proletarians has lost all individual
character, and consequently, all charm for the workman. He
becomes an appendage of the machine, and it is only the most
simple, most monotonous, and most easily acquired knack, that is
required of him. Hence, the cost of production of a workman is
restricted, almost entirely, to the means of subsistence that he
requires for his maintenance, and for the propagation of his
race. But the price of a commodity, and therefore also of
labour, is equal to its cost of production. In proportion
therefore, as the repulsiveness of the work increases, the wage
decreases. Nay more, in proportion as the use of machinery and
division of labour increases, in the same proportion the burden
of toil also increases, whether by prolongation of the working
hours, by increase of the work exacted in a given time or by
increased speed of the machinery, etc.”
