The Wolke et al (2013) study is among such studies to state that enough has not been made against bullying. They call for a total pull out from the thinking that "Bullying is a way of life" because it causes it does most damage to the players: Bully (i.e., psychopath), victims, and the more common bully-victims (i.e., former victims "taught" to be bullies from bullies). Damage continues to the adult life with risks more 6 times to be diagnosed with a serious illness, smoke regularly, maintain a job, or develop a psychiatric disorder.
It may also be a cultural problem. I usually approach the bully with a simple question "What is a big fella like you doing around younger kids? What is your business here?" Really though, what is an older guys business with children? They should be with their peers!
