That’s a headline women love to read about. Of course society is set up to make women miserable…the question is how exactly to undo it!
A discussion of this — triggered by the “women report lower happiness now than 1970, even though they earn more money now than 1970”

The reverse question seems it has an obvious answer — non-feminist though — women stayed home and were not expected to work (mostly did not work for money, hence the low income thing) in the 1960s. But low income didn’t make them poor, they were married.
So apart from existential “is my life meaningful” or Marxist “pleasure of work” angst, what’s really different then-vs-now? The work. Working makes you less happy.
