Which theory categorizes global inequality into core nations and periphery nations?

• A. World Systems Theory
• B. Stratification
• C. Socialization
• D. Me

Answer: (A)

World Systems Theory explains global inequality by viewing the world economy as a single, interconnected system with core, semi-periphery, and periphery regions. Core nations are highly developed, owning advanced industries and technology, and they drive economic activity that extracts value from around the globe. Periphery nations deliver raw materials and labor-intensive goods, often under arrangements that keep them economically dependent on core countries. The semi-periphery sits in between, industrializing but still tied to core-periphery dynamics. This setup helps account for persistent gaps in wealth and power between nations, because wealth tends to flow toward core nations through trade and structural dependencies. This contrasts with ideas focused on within-country hierarchies or how individuals learn social roles, which don’t specifically describe the global division of labor into core and periphery.
