Week political systems make it much risker to do business in Africa. Stupid people look at Africa as a growth opertunity's but few westerners got rich in Russa after the cold war. Weak government actually makes political connections more important just look at China.
Actually look to china for the model for exploitation in Africa arrangements established at the state for exploitation. You need political connections no doubt but Africa is no sob story at all. Its undiscovered gold.
