The average IQ level in Africa ranges from 60 to 80, which means that the people are not capable of living under a democratically elected government. Democracy only works if the people are intelligent enough to live under a democratic government. Else, military dictatorships suits them better.
Military dictatorships do never suit anyone whether it is in Africa or in North Korea or even in South East Asia.
What we see in some African countries happens also in the other part of the world but in a small size community. I am talking about gangs. Imagine the big boss letting another guy outside his family ruling, he will be killed and his family business will fall.
So when you make someone chose between living like a billionaire or a poor guy, it is obvious what he will chose. Besides some African leaders feel and act like they are the saviour of the nation from the western occupation so the old generation still believe in them.
Nowadays, people think outside the box drawn by these thieves which should took place decades ago...
