Why Africans are still late in development?

Our education is not up to the standard since it was established. Do you know why? The use of a foreign language in teaching our school children is responsible for this problem. We have, therefore, lost our real understanding as people and a nation. Africa will not, and cannot, rise in development unless we change our attitude towards the language to be used in teaching and learning. Competent and well-intended leaders are also necessary for development. African's leaders of today are jokers; they are not serious about the business of the nation. They do things in their own way for the sake of their selfish interests
