If women had not entered the workforce in massive numbers things could have continued based on old trajectories. The male breadwinner/housewife lifestyle was a formula that made it ideal for raising children cheaply, even if it didn’t seem like the most equitable.
If I had a good job and settled with a wife straight out of college I’m sure I’d be a father to two children by now. My income could easily support a non-working spouse and some kids.
But many of the women around me were not the type to settle so early, so I chased the money and ever more ambitious women. And with no family to support, I had dangerous amounts of money to spend on ever increasing prices and property.
And if I should marry a woman with equal earning power as me, we will be able to spend even more on whatever inflated prices are set before us. If you’ve ever been in a gay household with two men earning typical male salaries and no children, one thing you notice is that they always have tons of purchasing power. What do you think that does to the economy when it scales out?
