Forget Dangote and the rest of the billionaires, the richest people in Africa are politicians. Africans need to reevaluate and rethink their system, so much power is given to the politicians and without any checks or balances. How can an ex-governor not be tried in court for his mischievous activities because there is a written document that said so who signed the documents is it the populace? They loot millions of dollars and stack them up for their families whereas the masses are suffering.
They even go as far as banning the trading of cryptocurrencies because they feel people might benefit from it. When the world is enjoying it. African needs to be taken to the hospital and given proper treatment because they are moving backward. More strength to their youth as many are still thriving in the harsh environment.
You need to understand that what we see in many countries in the African continent is not democracy and instead it is just a bad parody of it.
When that happens and the government does not perform its main functions which are to keep people safe from internal and external threats and to enforce contracts then this is what happens, there is no incentive at all for people to create as everything can be taken away from them and the only way to make money is by becoming a politician and steal all the money that you can, this perpetuates the cycle and once you are in the cycle it is almost impossible to get out of it.
