I’m not sure if it was what you are going for, but one explanation is that the ever accessible dopamine hijacking building spreading machines of social media likely dilute the fuck out of parents influence.

Couple this with a new requirement of dual incomes to subsist.

So yes parents do have a role, and they are being squeezed out of it like a zit. The outcomes suck for everyone. I don’t know why it’s not mentioned, likely because it’s hard to ignore the egregious impacts of unfettered capitalism if you start asking these questions.
