Horsesh!t.
Africa was colonized for about 80 years.
Tell that to Estonia & Ukraine colonized for about 800 years.
Or
Czechoslovakia or Ireland colonized for about 400 years.
Or
Poland colonized for about 200 years.
Africa was colonized by white Europeans who did -- and continue to -- steal their natural resources from the native population.
White Europeans migrating across Europe is hardly colonialism, and the issue of racism wasn't NEARLY as stark. Regardless, it ain't like Ukraine, Estonia, and the Czech Republic are doing THAT great.
Finally, Africa suffered from a lack of arable land for much of its precolonial period, and it did not have the millennia of trade/crop rotation opportunities they had in the latitudinal commonalities of Eurasia.
