i respect your summary of the situation in Africa. It is/was very complex. Still there was some events that are not easily reconciled. I in no way want to see things in Africa fail for any reason but nonetheless there has been many problems. Blame it on whatever. Please do not blame it on whites in America. Everyone, everyone, wants to see Africans - Africans Americans succeed. Unfortunately, across the board this has not been the case.
There are a lot of whites who have really gone out of their way to prevent black people getting anywhere in America. Don't fool yourself. You might spend time time looking at France's role in Rwanda to resist the encroachment of anglophone culture. Congo was Zaire in those days. I can tell you from living with Africans who had equivalent education to me, they do not think differently, as a teen I would have entertained white brain difference but I learned that this was wrong. There was a very famous study by a professor of Queens University Belfast (Northern Ireland/UK) (also Oxford) which put Southern Irish school kids as having very low IQ scores. Well with no genetic changes and within their own lifetimes, the same students came to equal the previously thought superior Brits. Of course this professors work was highly suspect in his research however he became a darling of US white nationalists. Name escapes me this second. Edit :Chris Brand it was, you seem to be familiar with his work as your ideas seem identical much of the time. There is a thing called the Flynn effect, as it takes hold with black Americans you are in for a surprise. This is starting to happen. Beyond all that.. When I was a kid in the 70s I was told that as black Americans bore the curse of Ham / mark of Caanan (many confuse with Cain also) there was a religious duty to keep them underfoot as God intended. A very wealthy and powerful guy told me this, not my family thankfully. Racist culture is deeply rooted in the US and it will take more time.
Give me the list of the 100 African Americans so I can double check. 100 White Americans cannot find Florida on a map 100 On the Spectrum kids cannot spell their v. there
