Wage labor

Form taken by the vast majority of social work under capitalism.

Originally occasional in the pre-capitalist world, it became generalized with the accumulation of capital and the accompanying emptying of the countryside and industrialization.

Under these new conditions, the surplus labor extracted from the mass of the exploited takes place through the production and sale of commodities, and the exploited obtain, in return, the part of capital invested in ensuring the maintenance of their labor power, the wage.
