 The rise of capitalism, in separating the family household from commodity production, further solidifies this control of men over women in the family when the latter become economic dependents of the former in the male breadwinner-female housewife nuclear family form. Importantly, capitalism also creates the possibility of women’s liberation from family-based patriarchy by creating possibilities for women to work in wage labor and become economically independent of husbands and fathers. Engels stresses, however, that because of the problem of unpaid housework, a private task allocated to women in the sexual division of labor of capitalism, full women’s liberation can only be achieved with the development of socialism and the socialization of housework and childrearing in social services provided by the state. For this reason, most contemporary Marxists have argued that women’s liberation requires feminists to join the working class struggle against capitalism (Cliff 1984).
