During the 2016 Democratic Presidential primaries, Secretary Hillary Clinton and Senator Bernie Sanders were criticized for defining the American middle class as any household that makes $250,000 or less a year. At the time, the U.S. Census Bureau reported that the median income was $53,657 and the mean income was $75,738 for 2014. Would you agree or disagree with the Democratic candidates? How would you explain the median and mean income measures to the candidates?
