Why Americans Don't Hate the Income Tax

Gallup does a poll on Americans' views of the income tax every year, but this year it actually finds that a majority of Americans think the tax they pay is either "about right" or "too low":

But interestingly, the number of people who think the tax they pay is "fair" remains more-or-less unchanged at 60%. This suggests there are people who believe the tax they pay is too high, but nonetheless fair.

Is this cognitive dissonance? I suppose it doesn't have to be, since you can think the income tax is too high for reasons besides fairness. You might, for instance, think the income tax weighs down growth like a grindstone. But the first question is about how much individuals pay -- not whether the tax structure as a whole is too burdensome.

So I'll ask: Is there anyone who thinks the tax they pay is too high, but still fair? And why?
