Regarding Africa and its descent into corruption and I agree with Smokey that Western influence and colonisation totally screwed Africa.
The tribal system, although sometimes brutal worked for thousands of years. It maintained a sense of social order through the elder system and they lived off the land knowing nothing of the riches that lay underground, but once colonisation commenced, radicals were introduced such as modern weapons, the unearthing of immensely valuable minerals and of course with that came greed and the almighty dollar.
The west threw in political systems and laws that the indigenous people had no idea how to operate or control and once the colonisers got what they needed they were gone. What was left was anarchy and opportunistic cashed up twisted individuals who no longer had respect for elders or the tribal system now that they had a taste for the power and trappings of the western lifestyle and the only way they knew how to maintain this new lifestyle was through violence and the oppression of their own people.
