@doctorow the article I read about this stated that taxes were less for the vast majority of tax players, but the withholding calculation changed, so that someone may have taken home more money every month, but they end up having to write a check to pay for their lower tax bill.
People are just bad at math.
I think people would vote for different tax policy if they were good at math, but also if there was no withholding. These folks, it seems, are keeping more of their money, but dislike that they are more aware of the portion they have to pay to Washington.
