Schools and teachers cop the raw end of behaviour which often basically demonstrates the parents have never tried to teach their kids responsibility, respect, that actions have consequences or proper behaviour generally. Gotta say, you can't just assume that people on welfare are the worst parents either, as sometimes it's people who are quite successful in life who have the most irresponsible and arrogant attitudes.
You would be amazed at the way some parents behave, particularly in state schools where it's much harder to expel a bad kid than in a non-government school, where the parents have to sign a legal agreement to abide by the school rules, so if they repeatedly screw up or refuse to co-operate, it's actually breach of contract and the non-government school is totally able to say, "See you later".
That's one of the reasons there is a trend among responsible parents to send their kids to non-government schools, because good kids feel safer than in state schools. I have had parents and students tell me this. It's also why so many teachers are leaving the state system for non-government schools, as they feel the school will back them up in a confrontation.
