According to the latest Bureau of Labor Statistics figures, for the year from June 2013-June 2014, every single segment of American workers saw its income decline compared to the year before—except for the top 20% of earners.
The bottom 20% of earners saw their income decline 3.5%
The second 20% of earners saw their income decline 2.7%
The third 20% of earners saw their income decline 2.8%
The fourth 20% of earners saw their income decline 2.1%
The top 20% of earners saw their income rise by almost 1%.
The BLS does not break out statistics more finely, but it is a safe bet that a large portion of the gains of the top 20% of earners were driven by disproportionate gains for the top 10%, and the top 5%, and the top 1%, and the top 0.1%. This is the second straight year that average incomes have declined.
Consider the fact that over the same period of time that incomes were declining for at least 80% of Americans, the Dow Jones Industrial Average rose by more than 10%. Thus the owners of capital grow wealthier while the majority of people who live by their labor grow poorer.
