Context

“In this way this money returns to capitalist II as the money-form of his variable capital. An equivalent value of revenue in the form of money here replaces variable capital-value in the form of commodities. The capitalist does not increase his wealth by taking away again the money paid by him to the labourer in the purchase of labour-power when he sells him an equivalent quantity of commodities. He would indeed be paying the labourer twice if he were to pay him first 500 in the purchase of his labour-power, and then in addition give him gratis a quantity of commodities worth 500, which the labourers produced for him.” source
