Nowadays both men and women have the option of finding occupations that give them the most satisfaction. You might be surprised at how many people consider this progress.
If you have twice the labor, you can pay each person half as much (and double your profit) since consumption stays the same (to a rough approximation).
What you actually see is that with two full incomes housing prices went up. That's the supply side reacting to more money sloshing around. On the demand side, when both parents work there are now expenses for childcare, prepared food & so on.
You just have increased financial insecurity because now a family must rely on two incomes. In the past, when one spouse lost their job the other might find one or go to full time employment, now both parents have to be employed to be financially stable. That isn't even progress for those who have to work for a living. For the investor class it's of course different.
