Most men throughout the history of mankind have been genetic dead ends. In other words, their male lines died out, either because they could not reproduce children that women were attracted to sufficiently, or could not repridyce themselves.
Unmarried men die a lot younger than married men or unmarried women, so it's just genetics at play
I also know a lot of non working men in this age group. They seem so poorly motivated compared to women of the same age. Maybe the idea that there is marriage and a good job waiting for all men needs to be repositioned by educators, so these men are more prepared for the realities of the modern world.
I also know some working men born into quite favourable circumstances who have swallowed the red pill doctrine so that they have rendered themselves undatable, incapable of promotion and incapable of attracting more than unemployed women. Most of them are still single approaching their fifties, having revised to marry their plain unemployed girlfriend as they consider themselves too high a prize. Or they turn into passport bros and get themselves what is effectively a slave with brown skin from a poorer country.
