The document discusses dependency theory, which argues that resources flow from poorer "periphery" states to enrich wealthier "core" states. It originated in reaction to modernization theory. There are two perspectives on dependency - the capitalist view that it facilitates development, and the socialist view that it is a form of imperialism that enriches core states. Key aspects of dependency include globalization, free markets, surplus value flowing to core states, political and technological control by core states, and neo-colonialism. While it was influential in the 1960-70s, dependency theory has lost some influence with the growth of some developing economies, though still impacts anti-poverty campaigns.
