For many years, voters have told pollsters that they favor raising taxes on the wealthy, at least in theory. Last year, 62 percent of respondents told Gallup that taxes were too low on upper-income Americans, with 66 percent saying they were too low on corporations. Those numbers have changed little over the past 15 years. Numbers such as those explain why voters remain sour on 2017′s Tax Cuts and Jobs Act, which was a windfall for corporations and the wealthy.
