It's possible Feminists didn't for see how the labor market would use women entering the workforce to lower the standard of living for every one, but to say that these women are experiencing Schadenfreude is absurd. Schadenfruede is pleasure derived form the misfortune of others, what other's suffering would give these "Feminists" pleasure? To see other women suffer? They wouldn't be Feminists if they felt that way.I agree, corporations benefit materially, but you're reducing the whole of human interactions to that. Corporations simply couldn't force women into the workforce on their own, or even possess the ability to think to convince them. Feminists had to lay the groundwork, and they benefit by feeling vindicated in their own theories and worldviews. There's both a bit of shadenfreude and delerium for a Professor to be convinced they liberated women by sending them to call centers.
As far as most work being mind numbing I have to agree with you there. In fact most people I know would rather not go to work, and those that are working in their chosen field wouldn't mind working if they could just do it a few hours a week.
When it comes to staying at home I guess I am very lucky, perhaps it's because I live in area where there aren't many job opportunities so a lot of the stay at home moms I know are highly intelligent and either do not work outside the home or work very little. When we get together the topics range from civilization, structure of the English language, art, politics, math and physics. My husband never has such stimulating conversations at work.
We are also all homeschooling or unschooling moms so it's possible we are a less conventional section of the population.
