Personal responsibilty approaches to behaviour change have never worked and never will work. You might as well be shouting into the void for all the good it will do. You need to address these sorts of issues at the societal level.

I'm not sure if it was what you are going for, but one explanation is that the ever accessible dopamine hijacking bullshit spreading machine of social media is diluting 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.

You can argue that, but historically, how many men have been raised by strong women and still turned out to be misogynistic fucks?

The societal influences and behavioural trends will always outweigh the home environment

Once the kid is like 10, the outside world has like 90% of the influence on them. If anything the teachers are at fault. Cell phones should not be allowed in schools, and harassment of any kind should be immediately punished.
