It¡¯s mid-April, and Karlyn Bowman ¡ª the astute public opinion analyst at the American Enterprise Institute, a think tank located in Washington ¡ª has noticed something significant. Tax Day ¡°comes and goes without a ripple,¡± she recently wrote. There¡¯s not much fuss.

Discontent with the income tax has ebbed. To buttress the point, Bowman cited intriguing survey data. A recent Gallup Poll found that only 1 percent of Americans rated taxes the nation¡¯s top problem.

In a Pew poll, respondents ranked ¡°reforming¡± the tax system 16th out of 24 problems. Indeed, Gallup reports that roughly half of Americans think their income-tax burden is about right.
