This document discusses Andre Gunder Frank's dependency theory of development and underdevelopment, which argues that underdevelopment is caused by economic dependency on developed nations rather than internal deficiencies. It asserts that the world economy is organized to transfer economic surplus from poorer satellite nations in the periphery to richer metropolis nations at the core. While residents of developed nations benefit from higher standards of living as a result, the greatest gains go to capitalists in metropolitan countries and elites in satellite nations.
