This is not meant to be an offensive post, I am genuinely curious as to why Africa is so far behind the rest of the world.

The Roman Empire had running water, amenities, reliable shelter and clothing for its entire populace 2,000 years ago. 2,000 FRIGGIN YEARS AGO. They created art, sculptures, vast architecture using 2,000 YEAR OLD technology yet if you go to a random area in Africa, it is plagued by poverty, destitution and just overall squalor.

Why is Africa 2000+ years behind the rest of the world and what can be done to correct this??
