It’s acutally surprisingly obvious given the knowledge that it’s not the norm for men to have children, in evolutionary terms. So obvious it’s weird that there isn’t more focus on avoiding those outcomes in society.
Maybe it’s a leftover from agricultural society, where the institution of marriage reduced the tendency. I don’t prefer the strict marriage and fidelity norms of the past, but they certainly had a stabilizing effect. We don’t have a similarly effective stabilizer on the horizon.
All it takes is a look at those OkCupid studies for rating distributions to see how much larger the difference is between success and failure for men.
This problem is not exclusive to men, but affects more men.
Women more often have an expectation of mating upwards, and high status women have a similar problem of finding themselves excluded.
For that matter, you don't have to be with anybody at all, which may be why you see women rather be alone than follow parent's suggestion!
1. High status men have access to a lot of attractive women. With the way men's biology is wired, it wouldn't be surprising that they would choose an attractive, relatively lower status woman over a highly accomplished but not that attractive one.
2. High status men often have stressful work lives. They would probably prefer a partner that makes them feel relaxed at home. High status women usually have careers themselves so it would be difficult to provide this need.
So you'd expect anyone to get violent when they are starving or homeless, but only men to get violent if they don't see themselves getting a sex-partner in their future.
Also through large parts of human history females were treated as chattel and weren't subjected to the same pressures as males.
