"The question as to who, and what, is responsible for African underdevelopment can be answered at two levels. First, the answer is that the operation of the imperialist system bears major responsibility for African economic retardation by draining African wealth and by making it impossible to develop more rapidly the resources of the continent. Second, one has to deal with those who manipulate the system and those who are either agents or unwitting accomplices of the said system. The capitalists of Western Europe were the ones who actively extended their exploitation from inside Europe to cover the whole of Africa. In recent times, they were joined, and to some extent replaced, by capitalists from the United States; and for many years now even the workers of those metropolitan countries have benefited from the exploitation and underdevelopment of Africa. None of these remarks are intended to remove the ultimate responsibility for development from the shoulders of Africans. Not only are there African accomplices inside the imperialist system, but every African has a responsibility to understand the system and work for its overthrow."
