I read your post and I completely agree with you.
I remember while at college I was very amazed by the teaching staff, who were mostly Africans and taught Chemistry, Biology, Algebra, etc also some Indian professors, few as they were, taught mostly Algebra/math. At the hospitals I visited during school there were many African Specialists as well as some Indian Doctors as there were Caucasians.
This fact backs up your opening statements. There are many Doctors and Professionals that come out of Africa, and it is really taking a lot away from their country as a whole. For the ones that try to educate themselves outside of their country, it has been quite a lot of misery for them though, I have witnessed some of the struggle
and I really feel for these brothers!
