A professor with a doctorate from the University of Chicago, Sowell is largely considered to be one of the most influential American economists of the 21st century. Sowell conveys the nuts and bolts of free market economic theory against the backdrop of modern debates on income inequality and public policy, which he argues often underplay the production of wealth as a factor. Wealth production, Sowell claims with plenty of data in tow, relies on a confluence of complex factors including culture, demographics, and geography. Using historical events and measurable social trends as examples, Sowell shows the reader how different factors have influenced the economic trajectories of countries and people throughout history, and how they will continue to do so.
