The progressive historical role of capitalism may be summed up in two brief propositions: increase in the productive forces of social labour, and the socialisation of that labour. But both these facts manifest themselves in extremely diverse processes in different branches of the national economy.

The more the division of labor and the application of machinery extend, the more does competition extend among the workers, the more do their wages shrink together.

Be aware that the reward for labour, and quantity of labour, are quite disparate things.

The capitalist mode of production and accumulation, and therefore capitalist private property, have for their fundamental condition the annihilation of self - earned private property: in other words, the expropriation of the labourer.

In proportion as capital accumulates, the lot of the laborer, be his payment high or low, must grow worse.

The worker puts his life into the object; but now it no longer belongs to him, it belongs to the object.
