I genuinely don't understand this.
Inasmuch as while the history of humankind seems to be one rife with violent domination of one group of people by another there is usually some overriding order enforced. Or if not an overarching order then at the very least some general mindfulness to a larger picture.
Even when comparing to organized crime in the States...there are rules and a set of "laws" that are generally followed. Not exactly and not without violation, but there is a group enforcement of a base set of standards that provides the stability required to find growth and development.
But in so much of Africa is seems that there is nothing but senseless savagery and violence.
The wealthier nations absolutely feed it...but if I'm recalling my history of the continent correctly there was plenty of violence and savagery long before the first European colonists invaded and exploited the indigenous peoples.
