There was a magic period of time after electric-powered washing machines became ubiquitous, but before the market adjusted to women entering the labor force, when you could sustain a home on a single income, and women (and then men, too!) actually had a choice between staying at home to care for house & kids, and having a career. Alas, now the choice is gone, and everyone has to have a job. Sucks for the kids, as now both parents need to go to work, whether they want it or not.
