What is Andre Gunder Frank's Theory of Underdevelopment and show whether or not the theory can explain the state of development in many less developed countries today?

Andre Gunder Frank's theory of underdevelopment suggests that underdevelopment in many countries resulted from their historical interactions with developed countries, which exploited their resources and hindered their economic growth. While this theory provides insights into the root causes of underdevelopment, it may not fully explain the current state of development in many less developed countries today. Factors such as corruption, governance issues, and lack of investment in education and infrastructure also play significant roles in perpetuating underdevelopment.
