How does Dependency Theory explain the economic relationship between wealthy and poorer nations?

Dependency Theory explains that wealthy nations often maintain their power by creating a system where poorer nations rely on them for economic support and resources. This means that instead of developing their own industries, poorer countries may focus on exporting raw materials while importing finished goods from wealthier countries. For example, a country rich in minerals might sell those minerals to a developed nation, which then turns them into electronics or cars, selling them back at a higher price. This keeps the poorer nation in a cycle of dependency, making it hard for them to grow economically on their own. Ultimately, the theory suggests that to improve, poorer nations need to break this cycle and develop their own industries.
