Within the capitalist system all methods for raising the social productivity of labour are put into effect at the cost of the individual worker; all means for the development of production undergo a dialectical inversion so that they become means of domination and exploitation of the producers; they distort the worker fragment of a man, they degrade him to the level of an append into a age of a machine, they destroy the actual content of his labour by turning it into a torment; they alienate from him the intellectual potentialities of the labour process in the same proportion as science is incorporated in it as an independent power... But all methods for the production of surplus-value are at the same time methods of accumulation, and every extension of accumulation becomes, con versely, a means for the development of those methods. It follows therefore that in proportion as capital accumulates the situation of the worker, be his payment high or low, must grow worse.
