In Wages Against Women, Silvia Federici explores a number of different ways that women's work has not been remunerated. She argues that all unwaged work is an extreme form of exploitation, when considered within capitalism, a system based on the owners' exploitation of workers.
One of the most harmful effects of imposing housework on women is that
it has been transformed into a natural attribute of our female physique and personality . . . supposedly coming from the depth of our female character.
This concept of domestic as "natural" to women is harmful because it makes it far more difficult to sever the association, which according to Federici must be done.
Part of the "housework" burden is the emotional support women are expected to provide as wives and mothers. The variety of services in women's expected roles
create the specific character of that servant which is the housewife, that makes her work so burdensome and at the same time invisible.
It is in discussing the impact of waged housework on men, Federici makes the claim about women being slaves. She also says men will benefit from having the true nature of unpaid work exposed, which will show
the way capital has kept us divided and . . . against each other, we—their crutches, their slaves, their chains—open the process of their liberation.
