Corporations
Gangs, clans and militias are the smaller versions of corporations. The behavior of the poor and disenfranchised reflects the behavior of the rich and powerful who dominate and exploit them. The world, as dominated by atavistic war-based competition between heterosexual males, is bound to be violent, despite illusions of so-called capitalist democracy. Until the people of the world unite against the greedy and aggressive, as they have done historically nation by nation, there will be no real peace or general human evolution.
