If you have some time, HERE is a fascinating look at the way that income distribution has changed in the past 100 years. In 2013, the top 1% of households (households making more than $367,100) took home over 20% of all income! And the average income for the top 10% of households was $272,515, while the average income for the bottom 90% of households was $31,652. Compare that to 1973, when the average income of the top 10% was $162,467 (in 2013 dollars) while the bottom 90% made an average of $36,105. This is the growing income inequality in the US.
