I would have people fighting each other starting in kindergarten. People are relatively equal in kindergarten, and if everyone starting fighting each other from then, there would be less bullying, because people would constantly be competing against each other and there would be more equality. Imagine the educational benefits of people respecting each other in post-elementary school education. If people thought of violence as a good instead of an evil, the people who don't care either way wouldn't have so much power over those who do.
