My $0.02. Probably not much different...

In my opinion, it's just the "human condition". Like adults, kids want to take the least path of resistance. Since learning is difficult for some/most of us, avoiding school is the easiest path since it requires real effort. This is why parental guidance is so important for young people. Sure, some cities experience violence, some schools have odd teaching mandates, etc, but all-in-all, it's the daily grind that kids want to avoid (just like adults!). Not to mention the pressure from social media.
