Exactly. I was raised by two working parents who were very involved in my life, and I wasn't a "latchkey" kid by any means. While the "traditional" spouse at home does work out pretty well if the single wage earner can do well, to be sure. That doesn't mean other situations can't prosper. It's not a magically set up that is the solution for everyone.
Also no, women (or men) who stay home don’t “know best” by default. That knowledge is earned and requires intent.
