"It has become ever clearer that underdevelopment is the end result of a process. Therefore, it must be studied from a historical perspective, that is, in relationship to the development and expansion of the great capitalist countries. The underdevelopment of the poor countries, as an overall social fact, appears in its true light: as the historical by-product of the development of other countries. The dynamics of the capitalist economy lead to the establishment of a center and a periphery, simultaneously generating progress and growing wealth for the few and social imbalances, political tensions, and poverty for the many."
