Wishful thinking from the We H8 Whitey crowd at WaPo.
Absent massive material aid from the exterior of Africa, they will end up living in thatched huts on meager food supplies as their population outruns the capability of their ‘societies’ to feed them.
They will resort to collectivist solutions run by Big Chief Strongmen like South America, ending in food shortages, panics, massacres and chaos.
Throw in intertribal hostility and you get 1000 Rwandas.
The population will thus self control through the usual evolutionary mechanisms.
The easily farmable land is already in use. They can grow more using irrigaion and fertilizer, but the resulting food will cost more than Africans can pay.
Perhaps the Chinese will come in and play “cowboys and Africans”?
