But in any case investment in education is in itself a sign of an intelligent race. Africans have been on the planet as long as Chinese - but still they have never managed to build a functioning education system.
Chinese now massively outperform any other race in scholastic tests (see PISA tests). In UK schools, Chinese children outperform white children (particularly in science subjects) and of course Afro-Caribbean children are the poorest performers, and explains why UK overall scores are quite mediocre.
By the way, have you ever spent much time in Africa? You should try working there before you make any claims that they are just as intelligent as white people! I have spent some fifteen years or so working in various parts of Africa and I would never invest a penny in that continent, because the inhabitants are so dumb, venal, corrupt and dishonest.
