You're absolutely correct there, although the "until the 1960s most women were housewives" is pop culture copium. That was fully sixty years ago. Women's average political choices have gotten worse not better.

Single woman: "people I don't know should pay more tax to support my friend's art"

Married woman: "my husband should NOT pay tax to support people I don't know."

That is why women's votes change much more than men's after marriage.

Don't phrase it this way when applying for research grants or public office, but women on average are much more selfish than men on average.

People who want them to make better choices need to admit this and harness it.
