The nation's middle class, long a pillar of the U.S. economy and foundation of the American dream, has shrunk to the point where it no longer constitutes the majority of the adult population, according to a new major study.
The Pew Research Center report released Wednesday put in sharp relief the nation's increasing income divide, which is certain to be a central issue in the 2016 presidential race. It also highlights how various economic and demographic forces have eroded long-held ideals about maintaining a strong, majority middle class.
Many analysts and policymakers regard the shift as worrisome for economic and social stability. Middle-income households have been the bedrock of consumer spending, and many liberals in particular view the declining middle as part of a troubling trend of skewed income gains among the nation's richest families.
Median-income voters, particularly non-college-educated men, are also at the core of billionaire Donald Trump's surprising surge in the Republican presidential campaign. His supporters' sense that their once-secure middle-class standing is in danger of slipping appears to be fueling much of the anger against the government and immigrant groups.
