Dependency theory reflects the body of mid-20th century theories by various intellectuals, both from the Third World and the First World, that suggest that the wealthy nations of the world need a subjugated peripheral group of poorer states in order to remain wealthy. Dependency theory states that the poverty of the countries in the periphery is not because they are "not" integrated into the world system, but because of "how" they are integrated into the system.
