We agree about the last point, but daily violence doesn't mean you get beaten up everyday. It means there's a sufficient risk of it that you're scared everyday. That's not as uncommon as you probably think and it should be unacceptable, and I bet it would be considered unacceptable if that were the case at private schools (which it isn't).

violence at school is more an issue with American parents and the lack of decent morals and values

Isn't that a reason for American parents to homeschool, then? Or, move out of the country, I guess? It's not like I get to change the morals and values of all my neighbors.
