It's how it has been working in Africa until approximately 2016. I read somewhere, that for the longest time Africans had little opportunity to enrich themselves, so if they are in power. They have a very limited timeframe to fill their pockets enough for the rest of his life and his family, as well as kickbacks to the village he was born. Some leaders made their birth village the new capital, such as Ivory coast. Then again, the birth village of the leader is as good as any other choice, as long as it's somewhat central and protected against invasions from neighboring countries 😂
