Consider why Wallerstein thinks it's important to analyze globalization in historical stages. What happens in the periphery and semi-periphery of a world system for “core” countries to develop? To help your explanation, consider an example, identifying the role of a country in the world system, such as by a manufacturing label of a commodity you use daily (such as your sneakers, phone, or coffee).

Once we get a difference in the strength of state–machinery, we get the operation of 'unequal exchange' which is enforced by strong states on weak ones, and by core states in peripheral areas. Thus, capitalism is involved not only the appropriation of the surplus-value by an owner from a laborer, but an appropriation of surplus of the whole world-economy by core areas" (Wallerstein p.162).
