The proletarians have lost their innocence. A conservative sociologist once described wage labourers as follows:

The fact that this description – disregarding its formulation – is almost identical to the classical Marxist definition indicates a broad consensus regarding the characteristics of proletarians among intellectuals in the first half of the twentieth century. Implicitly, proletarians were considered to be male, were perceived in isolation from their families or households, and were associated with a “pure” social category: while personally free and without property, they were compelled to sell their individual capacities or skills for money. These proletarians were viewed not as abstract theoretical constructs, but (at least in the advanced countries and in the societies of “really existing socialism”) as concrete living people whose number was increasing rapidly by any standard. While some historians and social scientists may have suspected that workers could also be females, might live in families or households that combined several “coping strategies”, and sometimes had their freedom severely restricted by debts or other impediments, etc., these insights did not play a significant theoretical role.
