One of the deepest problems with being a man is the palpable, omnipresent sense that there are too many dudes. It is just a fact of the human condition that a large fraction of males are biologically superfluous. Society tries to equalize outcomes by promoting monogamy, but this strategy is losing effectiveness in the face of dating apps and extended premarital relationships. Historically, violence and war also tended to reduce the population of males, but violence has declined enormously compared to previous eras.

This isn't really the case! And, FWIW, it is neither true that monogamy is some clever invention nor that many women are meaningfully hypergamous. In all the high-quality data I see, women are just single more just as men are, they just don't talk about it as much in places you or I read (it seems like psychometrics implies the median woman is more okay with being single than the median man. Part of it could be that).
