I don't think you understand: poor women have never been able to afford to be a stay at home mother. Stay at home motherhood has always been a middle class and above lifestyle. Wealthier women employ the nannies and maids that are obviously overwhelmingly women who aren't at home.

I wouldn't attribute a lack of home stability to women empowerment. A lack of home stability is often caused by poverty. A poor mother cannot afford not to work, cannot afford suitable environments to raise her children while she works, and must make difficult decisions regarding proper nourishment/safe place to sleep/access to utilities/physical presence.
