Because Africans had to make a huge leap from primitive way of life to the modern one unlike Europeans or Asians which developed gradually over the last 3000 years or so. Some people might think it is a genetic gap that will never change but I think it can be done, it is just a long process of hundred years at best. There is also the issue of many African countries being a mix of more than one nation. It causes a lot of tribalism and favouritism and corruption. Uganda is a good example of how they got over it but still, diversity is a problem when there is more than one major group which sets the tone. Some western countries are going down this path thinking it will benefit them but it just makes things worst.
