From my own opinion, i think the colonial master should come back to Africa from Europe to completely reconstruct africa. Put in a good system of living there because what the leaders in Africa are doing is not at all convenient for the average Africans.
As a Nigerian who grow up from a normal African family, I know the quality of life there. You wouldn't know how the quality of life till you feel it. The countries have there rich politicians who try to cover most of the poor majority Africans so the outside world wouldn't know how things are.
If you want to know the truth how things really are in Africa, go there and as the average citizen how is the quality of life there.
As an African citizen who grow up in Africa and now studying in Europe, I can tell you that Africa only need an European intervention, Nigeria especially because as much as we hate to believe it, the Europeans are more advanced than US in implementing a better living condition (eg. good roads, jobs, health facilities, good system of education, allowance for the citizens since the money is there and so on)
Hope some one will listen.
