The shrinking middle class

Pew Research Center published this graph that shows how the portion of people in the middle class has shrunk from 60% to 50% of all Americans over the past 25 years. The calculation defined middle class as someone with a total household income ranging from $41,900 to $125,600 for a three-person household in 2014.
