Work is a practical teacher of the value of money, how to work together with people, and how to deal with an actual meaningful authority structure.
School has no way to teach the first, does not realistically teach the second, and makes any lessons with respect to the third meaningless between “no kid left behind”, the countless second chance opportunities given for breaking rules, and the fact that there’s no effective punishments offered for breaking rules.
I think many issues with young people (including my age and a little older) is that a lot of them don’t work until after highschool and have massive struggles with the transition of both having to work and being treated as an adult at the same time.
