So what happened after women entered the labor force? You can see the stats. Female wages increased, while male wages dropped massively. The drop in male wages was so large that even after including women, on average, young people today earn less than they earned in 1975. In other words the average young family today has less income than the average family from 1975, even though both spouses work.

What are the other negatives? Marriage is at an all time low. The majority are now not married. Hypergamy means that women won't marry men who earn less than themselves. Birth rates tanked below replacement level (1,76 for 2017). Homeownership is at an all time low. Lots of young people live with their parents because they can not afford to buy a home or get married.

So where does this end? Towards total destruction of marriage and single women backed by an enlarged welfare state using sperm donors instead of regular fathers? Are the men going to stay in such society or are they going to move to greener pastures?
