Perhaps they think they can't do it "right", so they won't even try.

I think you hit the nail on the head there, to be honest. It seems these newer generations are a lot more risk-averse and it seems to be related to their increased infantilization. There's a lot of talk I've heard about young people being afraid to take risks in their jobs and social lives without the go-ahead from "a grown-up", not recognizing themselves as such, and I imagine it ties into this childlessness epidemic also.

I like your comment a lot! I see it the same. It's why I'm not too crazy on this whole trend of blaming parents for not being perfect - parents are really just people doing the best they can, no? Some of them. And as long as you can know your folks did that, you should be happy, I feel.

Thanks for this lovely input! :)
