John Green is too stupid to figure out why Sierra Leone is so poor

Officially, SSA is no longer classified as “developing” because economists started feeling embarrassed classifying them that way, but it’s still colloquially known as “developing”)
5:56: That’s just a screenshot from the Wikipedia article on the four Asian tigers. It says basically the same thing as the 5:09 source. Just got a different picture for variety.

9:23: Many sources talk about how Sierra Leone gets hardly any revenue from mining
9:27: I’m not ignorant of the fact that if the government tried to nationalize the mines, America would bring them some freedom. But hopefully I won’t get too much pushback from saying that the Sierra Leonian government is incompetent.
