Context

“The capitalist does not buy the labourer’s means of subsistence but his labour-power. And that which forms the variable part of his capital is not the labourer’s means of subsistence but his labour-power in action. What the capitalist consumes productively in the labour-process is the labour-power itself and not the labourer’s means of subsistence. It is the labourer himself who converts the money received for his labour-power into means of subsistence, in order to reconvert them into labour-power, to keep alive, just as the capitalist for instance converts a part of the surplus-value of the commodities he sells for money into means of subsistence for himself without thereby warranting the statement that the purchaser of his commodities pays him in means of subsistence.” source
