A plurality of Americans are aware that income inequality has increased over the past decade, according to a poll by the Pew Research Center, but pinpointing the reason why is politically divided.

According to the poll, 26 percent of Democrats believe an unfair tax system is to blame for rise of economic inequality, while only 14 percent of Republicans agree with that assertion. In fact, the same number of Republicans believe inequality stems from congressionally enacted policies.

According to the poll, Republicans are also just as likely to believe that inequality stems from a bad work ethic among the poor (also grouped with government assistance programs) as they are to believe the unemployment rates are to blame. Democrats, on the other hand, rate low wages and the advantages of wealth as equally likely.
