Maybe you have also read that the distribution of men is wider spread out - more rich men, but also more poor men compared to rich women and poor women.

I think the pressure on men in society is simply higher. Women at least have their wombs, men only bring their achievements to the table. And traditionally women were loath to marry down, for example, whereas for men it was pretty common. I guess to prevent mass shootings, more feminists should marry down instead of complain about male competitiveness (which is 99% driven by women's choices, as mates is part of what men compete over).

I also seem to remember reading that the "running amok" thing also used to happen in traditional societies, so assuming it is a symptom of Neoliberalism is probably incorrect. The word "Amok" apparently is derived from a traditional culture: https://en.wikipedia.org/wiki/Running_amok
