Plus, you could also think about women entering the workforce as a shift to them getting paid for their labor finally, rather than all their labor being free to society. So is it wage stagnation or is it paying what you owe to the people who earned it?
Further, nobody ever considers the loss of the family farm during this time period. I guess it's just too easy to blame or put the burden on women; big surprise there. Look, all economic growth and production of a society rests on the shoulders of agriculture. Prior to 1960s the family farm provided that economic base. Then we shifted to Big Ag and everybody went to work in factories. This disrupted community flow of money and removed a lot of economic decision making and control from families. How do you think that affected wages? Almost immediately, those factories started getting shipped overseas to save money on labor. Again, how is that the fault of women? The fact is, women entered the workforce for a lot of reasons, including that the lost of the family farm left a lot of them unemployed for all intents and purposes.
There's a lot of factors at play here.
