Not as terrifying as starting your career in your 40s without an inherently marketable skill because 20s and 30s were spent playing video games...
Women also have more options.
>If that's your point, it's not going to be valid much longer the way things are going, with women dominating more and more of the middle- and upper-middle-class jobs (glass ceiling problem notwithstanding).
White and Asian women*
Step out of your HN bubble for a moment, and try to think about the existence of groups that you don't normally acknowledge. It's "not going to be valid much longer" just because things are changing in the immediate regions that you typically spend time reading about. There's the rest of the country and even the world to take into consideration too.
For women, losing their social network is losing a large chunk of their safety net (if they aren't receiving welfare otherwise), so it's almost unfathomable for them to do so of their own accord.
And perhaps because "taking care of themselves" pressure on women is much, much higher.
This is the Western countries' version of hikkikomori and there will only be more of it as education and good opportunities become out of reach for more people.
Men seem more likely to do this than women because of the societal pressures on them to get a job and run the rat race of dating and climbing a nonexistent corporate ladder.
For those people living in major job centers or major job creation industries it seems unfathomable, but there is an entire American generation out there experiencing this, being told that they're not shit if they don't go to college and work a 9 to 5 (which really is more of a 9 to 9). I don't blame them for opting out of such useless propaganda. Not everyone enjoys or is interested in computer programming, and starting your career in your 20s without an inherently marketable skill is terrifying for most people.
