As the variable capital always stays in the hands of the capitalist in some form or other, it cannot be claimed in any way that it converts itself into revenue for anyone.

When commercial capital occupies a position of unquestioned ascendancy, it everywhere constitutes a system of plunder.

Capital is dead labor, which, vampire-like, lives only by sucking living labor, and lives the more, the more labor it sucks.

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

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

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.
