Isnt nigeria basically the only african country right now that isnt a shithole right now?

Nigeria probably has the most theoretical wealth available to it because it’s super rich in oil, but there are definitely other countries that have it better than Nigeria (South Africa, Cape Verde, maybe Namibia or Kenya if you want some deeper cuts). Nigeria also has a metric fuck ton of problems (religious tension and sectarianism, terrorism, an openly corrupt political system which likely stole the last presidential election, and constant economic turmoil) that severely rob its capability to exploit its riches. and yes colonialism is a big part of that, it has fairly bad deals with major corporations to exploit that oil
