Who makes 56k and pays 27%? If they do, then they need to hire a new accountant. Or actually get an accountant.
You do realise that 14% is effective tax rate, not tax bracket don't you? And the average effective federal tax rate for americans is around 11-12%. For someone making 56k, its actually around 7%.
Romney pays a higher effective tax rate than the average american. He does however pay a lower tax rate than most in his tax bracket because of the nature of his income.
And the fact that he gave a shitload to charity....even if you don't like his charity.
