I read about this before I think it was on OKCupid study. The spoils go to the top. In the sexual market place, the top 20% of best/successful looking men, get most of the women on the dating apps. Leaving the hand as the best companion for the rest. Hence why Onlyfans is a billion dollar business. Pareto distribution at play again.

Also I read somewhere that only about 50% of men that have lived ever reproduced. And in societies with an unequal distribution, eventually devolves into being more violent. As the "incels", try to better their lot for reproduction.
