These charts are from the Pew Research Center. They show an economic problem in the United States. The rich have kept getting richer, and at a much faster pace than the rest of the population -- creating a vast and growing gap in both income and wealth.
We must fix this problem or we'll become a nation of "haves" and "have-nots". We are already more unequal than most other nations.
This has been caused by the GOP's trickle-down economic policy. A failed policy in which nothing trickled down (but just went to fatten the bank accounts of the rich).
We must change that economic policy to one where rising productivity is shared among all groups. Fair economics is smart economics, and contributes to a better country for everyone.
