Africa is poor, because it feeds the west and rest of the world through corruption. Africans are taught corruption by the colonial empires.
In my school days I had the crazy idea that I wanted to get an MBA after my BS in engineering. To enter business school you had to at minimum take classes in accounting, micro, and macro economics. I clearly remember the macro-economics text book stating that African countries were poor because they did not contain enough rich people. I slammed the book closed and took it back to the campus book store for a refund. I completed the class without a textbook.
