Women have been responsible for most of the domestic labor throughout history. Over the last 100 years or so, economies have changed so that women were first able to work outside of the home, then expected to work outside the home, and now need to work outside of the home. (E.g., a single-income household can't pay the minimum bills in most places in the US.)

But doing labor outside the home means that labor can't be done inside the home, because time is a finite resource; if you're working 40 hours a week (plus commuting time), that's 40 hours you don't have for raising a family. That makes raising a family significantly more difficult.

The solution is to change the structure of the economy so that it's entirely reasonably possible to raise a family on a single income without living in grinding poverty.
