>>1830853>>1830856Surplus-value is the social product which is over and above what is required for the producers to live.
The measure of value is socially necessary labour time. Each particular commodity represents only a certain share of the socially necessary labour time. The magnitude of value is determined by the amount of socially necessary labour, or by the labour time that is socially necessary for the production of a given commodity, of a given use-value. Surplus value is the accumulated product of the unpaid labour time of the producers. In bourgeois society, surplus value is acquired by the capitalist in the form of profit: the capitalist owns the means of production as Private Property, so the workers have no choice but to sell their labour-power to the capitalists in order to live. The capitalist then owns not only the means of production, and the workers’ labour-power which he has bought to use in production, but the product as well. After paying wages, the capitalist then becomes the owner of the surplus value, over and above the value of the workers’ labour-power.
Labour-power is the combination of mental and physical capabilities existing in a human being, which one exercises whenever one produces a use-value of any description.
In order that labor power is a commodity, the following conditions must be met:
1: The individual whose labour-power it is… sells it as a commodity. In order that he may be able to do this, he must have it at his disposal, must be the untrammelled owner of his capacity for labour, i.e., of his person. He and the owner of money meet in the market, and deal with each other as on the basis of equal rights, with this difference alone, that one is buyer, the other seller; both, therefore, equal in the eyes of the law. The continuance of this relation demands that the owner of the labour-power should sell it only for a definite period, for if he were to sell it rump and stump, once for all, he would be selling himself, converting himself from a free man into a slave, from an owner of a commodity into a commodity.
2: the labourer instead of being in the position to sell commodities in which his labour is incorporated, must be obliged to offer for sale as a commodity that very labour-power, which exists only in his living self.
For the conversion of his money into capital, therefore, the owner of money must meet in the market with the free labourer, free in the double sense, that as a free man he can dispose of his labour-power as his own commodity, and that on the other hand he has no other commodity for sale, is short of everything necessary for the realisation of his labour-power.
