Thanks. Wanna point out how?
because its not as black and white as you tried to paint it... there was warfare between tribes long before we got there... tribal leaders actually sold africans into slavery to whites... AIDS actually comes from africa, so they gave it to US... etc.
Because they didn't have technology, because they didn't need it, because technological prowess does not mean success, because their way of life was fucking fine before we got there and fucked their shit up with slavery and war?
I am no expert, but I don't think "Europe" is unique in technological advancements. Many European advances in Technology, Sciences, Medicine were influenced by or started in Asia, The Middle East, Africa (ie. Eqypt). Also wasn't the entire Roman civilization's foundations based on slavery, also slavery has been a major part of Europe's history way before African's were brought to the New World.
. I wouldn't be surprised if Africa had become much like Australia (as far as I understand it. I'm talking about the continued existence of aboriginals.), a few major, technologically advanced cities, some smaller modern towns, and small villages that retained the original culture, with access to medicine and other things.
