Why does poverty persist even when economic development takes place? The means to end it exist, according to this analysis, but corruption and the abuse of power stand in the way. The author goes to some length to stress the importance of including social change and the understanding of cultural factors in development efforts, but he has disappointingly few explanations of how rich and poor are to be motivated to create the missing political will. Perhaps that is because, as he says, "There is no blueprint for development policy."
