Kids emulate adults…

I would generalize that more to, "People operate and react to the system they're in." For kids, a huge part of that is their parents, but there are other factors involved like social media, and the wider society.

So many people want the simple answer, so they say it's "personal responsibility" and nothing else. We need to create/adjust our systems to generate the outcomes we want. As you point out, socioeconomics play a huge part so we not only need to relieve those burdens, but also provide specific supports in schools and the wider communities.
