"The circumstances of African trade with Europe were unfavorable to creating a consistent African demand for technology relevant to development; and when that demand was raised it was ignored or rejected by the capitalists. After all, it would not have been in the interests of capitalism to develop Africa. In more recent times, Western capitalists had refused to build the Volta River Dam for Ghana under Kwame Nkrumah, until they realized that the Czechoslovakians would do the job; they refused to build the for Egypt, and the Soviet Union had to come to the rescue; and in a similar situation they placed obstacles in the way of the building of a railway from Tanzania to Zambia, and it was the of China that stepped in to express solidarity with African peasants and workers in a practical way. Placing the whole question in historical perspective allows us to see that capitalism has always discouraged technological evolution in Africa, and blocks Africa’s access to its own technology. [...] Capitalism introduced into Africa only such limited aspects of its material culture as were essential to more efficient exploitation, but the general tendency has been for capitalism to underdevelop Africa in technology."
