The increase in economic disparities over the past 30 years has prompted extensive research on the causes and consequences of inequality both in the United States and, more recently, globally. This review provides an update of research on the patterns and causes of economic inequality in the United States, including inequality of earnings, wealth, and opportunity. We also explore the social and political consequences of inequality, particularly in the areas of health, education, crime, social capital, and political power. Finally, we (...) spotlight an emerging literature on world inequality, which examines inequality trends within as well as across nations. Sociologists can advance research on inequality by bringing discipline-based expertise to bear on the organization and political economy of firms and labor markets, the pathways through which inequality has an effect, and the social, political, and cultural contingencies that might modify this effect.

The global financial crisis that started in 2008 was followed by recessions, austerity measures, protests, and demonstrations. Relative deprivation theory offers an explanation as to why people engage in protests and violence, and the literature contains evidence that economic and environmental variables are often to blame. However, previous RDT scholars have not investigated how a country’s entrepreneurial attitudes can affect increases in civil disorder, which is the primary purpose of this study. The authors’ results provide not only conflicting evidence regarding (...) RDT explanations but also strong evidence that high levels of entrepreneurial attitudes can significantly dampen increases in society’s level of civil disorder. Levels of environmental degradation were found to have no impact on changes in civil disorder. (shrink)
