How does Dependency Theory explain the economic relationship between core and peripheral nations?

Dependency Theory explains that core nations, which are more developed and industrialized, often rely on peripheral nations for raw materials and cheap labor. This relationship creates an imbalance where peripheral nations become dependent on core nations for economic growth, but they often do not receive fair benefits in return. For example, a country rich in natural resources, like oil, may export its products to a core nation, but it might not develop its own industries or improve its economy significantly. As a result, while core nations grow richer, peripheral nations may struggle to escape poverty and improve their living conditions. This theory helps us understand why some countries seem to get richer while others remain poor, highlighting the unfairness in global trade practices.
