Resumo

The author criticizes the theses according to which the labour force is produced outside the capitalist production process. In the model he proposes the family-wages covers both the production of goods and services and the production of labour force. The proletariat considered as input produces surplus value and considered as output embodies surplus value. The author analyses the relationships between the labour force as output and as input. He also intends to show that the market role m the capitalism is minor and the state role is the central one. In changing from output to input the labour force is devalued by the process of the relative surplus value. At last he analyses some implications of this model as far as thc social struggles are concerned.
