Just got back from filing my taxes--well, my extension, to be honest. And while we all like to bitch and moan about them, it's worth noting that income taxes really do soak the rich, while the rest of us get a pretty decent deal. Not as good a deal as we used to get, because the Bush tax cuts overwhelmingly favored the wealthiest people in the country, but the rich still pay a huge percentage of the federal government's take.
I've written about this before, here and there, if you're feeling all wonky and want to learn more. But to sum it up: Getting rid of the federal income tax and going to a sales tax would be a huge tax increase for most Americans, and every time the Arizona Legislature does an across-the-board income-tax cut, the wealthiest Arizonans make out very well, and the average Arizonan gets peanuts.
Remember that the next time you're stuck in traffic on the Interstate and wish there was a third lane between here and Phoenix.
