School are places to learn
If you are not there to learn then you should not be in the school. Period.
Just send troublemakers home.
People who want to learn should be the only ones allowed in schools. Education is a privilege, not a right.
There is a complex picture here. Parents who don’t care send their kids to the school as a baby sitter. So teachers inherit the role of godparents too, whether or not they want it.
Kids always learn SOMETHING at schools. It just might not be the lessons that classic educators intend.
And too... when everybody is taxed for this “privilege” then indeed it starts looking a lot like an entitlement after all.
