Dependency theory
Dependency theory states that poor nations provide natural resources and cheap labor for developed nations, without which the developed nations could not have the standard of living which they enjoy. When underdeveloped countries try to remove the Core's influence, the developed countries hinder their attempts to keep control. This means that poverty of developing nations is not the result of the disintegration of these countries in the world system, but because of the way in which they are integrated into this system.
