"Your kids should take one for society" is an atrocious pitch.

"Your kids should be stuck with people who ruin their lives because criminals are" is also terrible.

The correct response is moving problem kids to problem schools, then to disciplinary schools, and if necessary to juvy.

Put people where they belong, with the people they belong with.

Otherwise the people stuck with the trash will leave (and maybe that's okay in the end)

Most problem kids can be rehabilitated with some investment of time in a positive, welcoming environment though. Not so much if you stick them in prison school. They’ll just live up to your expectations in that case.

Most of the time, there's no rehabilitation. These kids just ruin some other kids' lives.

Then the problem is there is no rehabilitation isn’t it.

It’s not like those kids were born genetically terrible.

Often dangerous inmates are moved to higher security prisons. Gang members are segregated, etc.
