Have you noticed that the more money people make - the more things cost? In the good old days, my father supported the family while my mother stayed home to raise the kids and run the household. We lived in a blue collar neighborhood and for a time only had one car, one television, and one window air conditioner - but we lived the good life!
Then "feminists" started burning their bras and telling other women they were being oppressed and couldn't be completely "fulfilled" until they had a career outside the home. Mothers were embarrassed to say that they didn't work outside of the home. That was the start of "latch-key" kids, growing divorce rates and the decline of public education. Prices of homes, food, clothing and everything else went up so much that it REQUIRED two incomes just to keep up with the Joneses.
We didn't know how good we had it back then.
