There are plenty of respectable arguments to have about the estate tax. But the Washington Post's Ezra Klein recently made a pretty ridiculous claim:
So if you hear politicians worrying about the 55 percent rate, remember that when it was last in place, fewer than 5,000 people were affected every year. It’s simply not that big a part of the tax code, and the idea that “millions” of families and small businesses would be affected by a return to Clinton rates is just plain wrong.
You cannot measure the importance of a tax by how many people pay it. A better question is: how many people pay to avoid it.
