63% of men ages 18-29 are single. For women it's 34%, which is still a lot.

Theres a few reasons for this.

1 is that Zoomer men are generally less masculine than Millennial men: Most were raised in single mother households, and grew up in a society where masculinity was castigated. They did not have strong male role models while growing up, not even in television or movies. Zoomers grew up in a world saturated with electronic devices and the internet: They spent less time outside socialising with their friends, going to partys, getting in fights, going on dates, etc. Basically, they were deprived of the formative experiences that Millennials still got to enjoy.

2 is that Zoomer men are poorer than Millennial men. Many of them aren't holding down a steady job. Even if they are working, they are less motivated than men even 10 years ago were, because Millennials still had the illusion that they could have a wife and family, while Zoomers have accepted that this is a fantasy. Even if Zoomer men are working hard, they haven't had the time to build up money or resources that Millennial men have. Women generally avoid broke men, unless they are charismatic and handsome.

3 is that online dating has fundamentally unbalanced the entire sexual marketplace, to womens benefit and mens detriment. It enables women to sift through arbitrarily large numbers of potential suitors without ever having to meet them in person and invest any effort on their part, in order to find the few top men who meet their arbitrary criteria. Whereas Millennial men only had to compete against the men in their own city, Zoomer men need to compete against the men from all over the country. Increasing the level of competition to that extent inevitably means there will be more drop outs.
