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 directing motive, the end and aim of capitalist production, is to extract the greatest possible amount of surplus value, and consequently to exploit labor-power to the greatest possible extent.

An increase in the productivity of labour means nothing more than that the same capital creates the same value with less labour, or that less labour creates the same product with more capital.

The circulation of capital realizes value , while living labour creates value.

As a beast of toil an ox is fixed capital. If he is eaten, he no longer functions as an instrument of labour, nor as fixed capital either.
