The capitalist cannot store labour-power in warehouses after he has bought it, as he may do with the raw material.
Trade unions and strikes cannot help in times of crisis when there is no demand for this “commodity”, they cannot change the conditions which, convert labour-power into a commodity and which doom the masses of working people to dire need and unemployment. To change these conditions, a revolutionary struggle against the whole existing social and political system is necessary; the industrial crisis will convince very many workers of the justice of this statement.
Unlimited exploitation of cheap labour-power is the sole foundation of their power to compete.karl marx
The labour-power is a commodity , not capital, in the hands of the labourer, and it constitutes for him a revenue so long as he can continuously repeat its sale; it functions as capital after its sale, in the hands of the capitalist, during the process of production itself.karl marx
