As pointed out by Nelson (1993 and 1996), it advocates a movement in the central focus of economic analysis away from trade and choice to provisioning, i.e., to the goods and processes necessary for human survival. This is what is done by Picchio (2001 and 2005), who is concerned to define the process of social reproduction of the population and situate it within the dynamic of the economic system. In the case of paid work, the indicator used to identify this condition is a set of commodities conventionally considered necessary for the reproduction of workers and of the working population as a “species”. A separation has arisen between the two in the capitalist system, and this has led to the creation of separate spheres, institutions, social organizations, norms and even cultures that distinguish paid work from unpaid reproductive work.
