If you don't educate people well, then you're going to have a lot of violent, angry young men and women. You can go around saying they're all so violent, just throw them in jail, this is an underclass, what can you do? You can create fear. The issue of violence is very suitable for a repressive society. Then you can have more legislation, more police, more laws to fight crime, when all you need to do is to encourage people in a different way.
