Capitalism subordinates men to machines instead of using machines to liberate men from the burden of mechanical and repetitive work. it subordinates all social activities to the imperatives of an incessant drive for individual enrichment in terms of money, instead of gearing social life to the development of rich individualities and their social relations. The contradiction between use-value and exchange-value, inherent in every commodity, fully unfolds itself in this contradictory nature of capitalist machinery. When capitalism is not overthrown once it has created the material and social preconditions for a classless society of associated producers, this contradiction implies the possibility of a steadily increasing transformation of the forces of production into forces of destruction, in the most literal sense of the word: not only forces of destruction of wealth (crises and wars), of human wealth and human happiness, but also forces of destruction of life tout court.
