According to the Physiocratic school that prevailed in France in the XVIIIth century, economy is based on nature. In fact, Physiocracy means “domain over nature”. Therefore the physiocrats believed that economy was ruled by a natural order and that nature alone (land, mineral quarries, etc) was the source of wealth. Francois Quesnay, the main representative of the physiocratic school, retained in his famous Tableau économique that only land was productive and therefore that only land owners had the rights to the net profit. In fact the only kind of profit that Physiocracy admits is the income of natural goods, while it denies any other type: the capitalist’s gain and the workers salary (Ricossa 1982, p. 197). For what concerns labour, physiocrats thought that it did not produce a net profit, but only a part of the production (gross income) necessary for the biotic consumption of the worker and of his relatives, that is the part necessary for the survival and reproduction o...
