Global Income Inequality and Marxist International TheoryIntroductionA study reported by the World Institute for Development Economics Research at the United Nations University, 40% of global wealth it is held by 1% of adults in 2000, and the top 10% of adults accounted for 85% of the world total. The bottom half of the world's adult population holds nearly 1% of global wealth. These include income inequality. Income inequality can be divided into two types: inequality within countries and inequality between countries. In this paper, inequality between countries was chosen as the focus of the studies. In addition to the internal factors of countries, there are many external factors that lead to income inequality between countries in the context of globalization. There are two interesting observations: the north-south pattern in income distribution and developing countries with high gross national product (GNP) but low per capita GNP: underdevelopment. Some have suggested that it arises from the mechanism of world trade. We want to delve deeper into these observations through the theory of Marxism. In this essay, the theories of Marxism in international perspectives will initially be briefly introduced. Secondly, the North-South divide and underdevelopment in less developed countries will be described. In the last part, this article tries to use the theories of Marxism to explain these phenomena and evaluate their applicability. Conceptual tool Before analyzing the case in reality, we first introduce the theories of Marxism associated with international relations. MarxismTradition MarxismMarxism is a socioeconomic analysis of class relations and conflicts based on the critique of capitalism.

The North-South divide is divided by economic power rather than national border as well as by consideration of the economic factor. And Lenin's theory of imperialism can explain the process of exploitation of less developed countries that provide raw materials and labor. The less developed countries are the producers and the more developed countries are the capitalists who provide capital and resell the final products to the less developed countries. The capitalists (more developed countries) squeeze the producers (less developed countries) by cutting payments and welfare. It adds the global dimension to traditional Marxism and explains the process of global exploitation. However, From the explanation of Dependency Theory, Using World Systems Theory.Reference
