Core nations control and profit the most from the world system through military, economic, and political power. They are wealthy states that exploit resources and labor from peripheral countries for their own benefit. Examples of current core powers include the United States, Western European nations, Japan, Australia, and New Zealand. Peripheral nations have limited industrialization and are exploited for their raw materials and cheap labor, resulting in underdevelopment and poverty. Semi-peripheral nations have some characteristics of both core and peripheral countries and serve as a connection between the two, facilitating trade and alleviating political pressures.
