Another one adding to your point is huge number of women entering the workforce all at the same time. You are drastically increasing families' spending power and discretionary income = inflation. Of course, when you double the supply of something, the price drops, which could partially explain stagnating wages. But in the early post-WWII decades it was a big win. Nowadays the negative consequences of moving away from traditional family roles are more obvious.
