Ok, how about how liberal divorce laws and the sexual revolution led men to think they were not necessary, leaving women to raise their kids alone on welfare?
Smart men are staying single or doing their wife shopping in the Orient.
The feminism sword is double edged. Free sex with no worries of pregnancy means the same for men. All fun and no responsibility. And of course, no commitment. Many men like that.
Extreme feminists probably end up old and bitter and lonely. I wonder how many have regrets when the “clock” has wound down.
