Under capitalism workers are exploited because the value they create working is greater than the value included in their wages. The exploitation of workers leads to their oppression. There is no doubt that the oppression of women affects all women. Women are pressured into subordinate roles in the family through moral codes, religion and popular culture. The law, the state and the family all regulate women's fertility.
Women earn less than men.
Millions of women are battered, abused and raped. Not all women are exploited. Some women do not have a job outside of the home, others are managers and bosses. But all women are oppressed. Oppression has existed as long as society has been divided into classes, with one group owning property and gaining rights to use that property for their own ends.
