Washington essay: US middle class shrank and professor lamented widening gap of rich and poor.

An essay on the diminishing U.S. middle class is presented. It offers a history of declining middle-income American families from 1971 to 2015 and examines how the U.S. Congress caused shrinkage of the middle class in bipartisan disputes where Democrats speak for benefits of the poor industrial workers while Republicans fight for interests of the rich. The author relates the way political candidates uphold the middle class during campaigns and how they will be true to their word when elected.
