I am from Africa. I can say first-hand that most aren't interested in scientific and technological pursuits. However, I can make the same claim for white people

I am from Africa. I can say first-hand that most aren't interested in scientific and technological pursuits. However, I can make the same claim for white people. The difference between us is access to great education and resources. I was fortunate enough to grow in a wealthy family and have access a great education. This African "middle-class" you speak of is almost non-existent please care to check for Th GDP per capita of most African nations and dare say THAT is not lower than the norm.
