Botswana is one of the reasons that I will shit on racial ideas. The problem of Africa is not that they are black, it's that most of the countries there went through communist revolutions. Botswana became pretty liberal and was completely fine, with a majority black population, and being able to create a functioning country.
Here's the thing, black people aren't stupid from nature. There are many smart black individuals. But the thing is, that socialists keep them stupid for their own personal gain.
They keep them in poverty through foreign aid.
They keep them from trying in USA due to their shitty laws that partially favor them and partially treat them like shit.
I believe if you cut off foreign aid, and allowed Africa to sort itself out, it eventually would. Through pain, blood and sweat but it eventually would.
Imperial powers fucked up Africa by violating the NAP of the populaces there and now the socialists who spend our taxes on foreign aid are making things worse.
Racialist studies are garbage, and the idea of "race" is collectivist bullshittery. Give individuals the freedom to decide for their own and they will improve their situation no matter the race.
