In the United States, the top 1 percent of income bracket takes home significant portions of annual national income and owns about a third of the nation's wealth. But scholar Richard Reeves argues a more significant divide is found in the upper-middle class, between the top 20 percent and everyone else. In his new book, called "Dream Hoarders," Reeves suggests the advantages gained by this group is the result of certain policies and behaviors that protect their status and keep others out. Those advantages also extend to our school systems, where inequalities can be seen across the country. NewsHour's Hari Sreenivasan spoke with Reeves about his book.
