I think it's because they don't get ahead even if they do the 996 work week.

Guys can't find wives there due to shortage of women and women's expectations. women can't get married after they reach around 28 years old unless it's to an old fag like the guys on poal, lol.

So they decide to just do the minimum and survive.

No. These are the ones who realize china's commie system doesn't value meritocracy. They know they'll never get ahead.
