Just as the United States' wealth is increasingly concentrated among its richest citizens while the middle class slowly disappears, global inequality is concentrating resources in certain nations and is significantly affecting the opportunities of individuals in poorer and less powerful countries. In fact, a recent Oxfam (2014) report that suggested the richest eighty-five people in the world are worth more than the poorest 3.5 billion combined. TheGINI coefficient measures income inequality between countries using a 100-point scale on which 1 represents complete equality and 100 represents the highest possible inequality. In 2007, the global GINI coefficient that measured the wealth gap between the core nations in the northern part of the world and the mostly peripheral nations in the southern part of the world was 75.5 percent (Korseniewicz and Moran 2009). But before we delve into the complexities of global inequality, let’s consider how the three major sociological perspectives might contribute to our understanding of it.
The functionalist perspective is a macroanalytical view that focuses on the way that all aspects of society are integral to the continued health and viability of the whole. A functionalist might focus on why we have global inequality and what social purposes it serves. This view might assert, for example, that we have global inequality because some nations are better than others at adapting to new technologies and profiting from a globalized economy, and that when core nation companies locate in peripheral nations, they expand the local economy and benefit the workers.
Conflict theory focuses on the creation and reproduction of inequality. A conflict theorist would likely address the systematic inequality created when core nations exploit the resources of peripheral nations. For example, how many U.S. companies take advantage of overseas workers who lack the constitutional protection and guaranteed minimum wages that exist in the United States? Doing so allows them to maximize profits, but at what cost?
The symbolic interaction perspective studies the day-to-day impact of global inequality, the meanings individuals attach to global stratification, and the subjective nature of poverty. Someone applying this view to global inequality would probably focus on understanding the difference between what someone living in a core nation defines as poverty (relative poverty, defined as being unable to live the lifestyle of the average person in your country) and what someone living in a peripheral nation defines as poverty (absolute poverty, defined as being barely able, or unable, to afford basic necessities, such as food).
