Feminism was motivated by the minority of women that wanted a job in 1950, and their legitimate frustration with how the system was trying to stop them from doing that. Somehow that got switched around into a society where almost every woman is required to have an income. It's like we went from oppressing half of all women to oppressing the other half of all women.
It's a form of prisoners dilemma. "Cooperating" with traditional society meant being a single-income couple. "Defecting" is being a dual-income couple. Once enough couples start defecting, they're so much more competitive that other couples have to defect to survive.
