Steve Shirley https://en.wikipedia.org/wiki/Steve_Shirley was able to found a computing consultancy business in the 1960s staffed entirely by women that had been fired when they got married, as was the usual practise at the time.
This is an amazing story I've never run across. Thank you for pointing it out. I think you got trolled, but I'm glad I got to learn about this as a result.
It was the norm for banks in New Zealand, through to the sixties and early seventies, to require women to have a letter of permission from their father or husband in order to get a job.
I'm talking about forming all-married women businesses. I'd be shocked if that was common, but if you have data showing otherwise, I'm happy to be corrected...
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.
