Final answer:
Dependency theory explains global inequality as the result of core nations exploiting semi-peripheral and peripheral nations, creating a cycle of dependence. Core nations exploit the resources and labor of middle-income and low-income nations, preventing their economic growth.
Step-by-step explanation:
Dependency theory explains that global inequality is caused by dominant core nations exploiting semi-peripheral and peripheral nations, creating a cycle of perpetual reliance. According to this theory, core nations, which are high-income nations, exploit the resources and labor in middle-income and low-income nations, perpetuating their own economic dominance. This theory suggests that as long as peripheral nations are dependent on core nations for economic stimulus and access to the global economy, they will never achieve stable economic growth.
