Sure but class inequality is what exacerbates gender inequality. Under capitalism anyone who is working class is forced to sell their labor to survive. Women are inherently disadvantaged here because their labor is required for social reproduction. Even assuming an equal distribution of housework and raising kids women have to do the unpaid work of pregnancy, childbirth, nursing, etc. Capitalists will therefore discount the value of a women’s labor regardless of her individual capabilities or productive output. As a result women are often forced to depend on the men in their lives for financial stability.

Conservatives are hell bent on normalizing this unnatural inequality between the sexes because doing so protects the underlying class inequality between owners and workers. This is what helps to create a sexist culture that even wealthy women have to endure. However, a woman who can live off of the growth of her investments is not facing the full weight of gender inequality that a working class woman must contend with. She does not have to deal with the threat of homelessness, hunger, and poverty that keeps many working class women dependent on men. Her financial stability is already assured because of her class position and the exploitation of the working class. That gives her far more freedoms than even most working class men.

The obvious solution to the problem is to upend capitalism which is what reinforces class. That creates the possibility of actually valuing reproductive labor and giving universal financial independence to all women. If you just try to address gender inequality alone without upending capitalism you won’t be able to succeed. Even if somehow you did, the vast majority of inequality would remain because most inequality can be explained by class alone. So while its true that gender and class issues are interrelated, abolishing class creates the conditions necessary to abolish gender inequality.
