Everywhere the proletariat develops in step with the bourgeoisie. In proportion, as the bourgeoisie grows in wealth, the proletariat grows in numbers. For, since the proletarians can be employed only by capital, and since capital extends only through employing labor, it follows that the growth of the proletariat proceeds at precisely the same pace as the growth of capital. Simultaneously, this process draws members of the bourgeoisie and proletarians together into the great cities where industry can be carried on most profitably, and by thus throwing great masses in one spot it gives to the proletarians a consciousness of their own strength. Moreover, the further this process advances, the more new labor-saving machines are invented, the greater is the pressure exercised by big industry on wages, which, as we have seen, sink to their minimum and therewith render the condition of the proletariat increasingly unbearable. The growing dissatisfaction of the proletariat thus joins with its rising power to prepare a proletarian social revolution.
