Karl Marx,
Wage-Labor and Capital
(1902)
“ Capital can multiply itself only by exchanging itself for labor-power, by calling wage-labor into life. The labor-power of the wage-laborer can exchange itself for capital only by increasing capital, by strengthening that very power whose slave it is. Increase of capital, there- fore, is increase of the proletariat, i.e., of the working class. And so, the bourgeoisie and its economists maintain that the interest of the capitalist and of the laborer is the same. And in fact, so they are! The worker perishes if capital does not keep him busy. ”
