Here’s a little something to chew on while you get your income tax files together this season. Median income in the USA is $48,000. Average annual income of the top four hundred taxpayers? Two hundred and fourteen million dollars. Yep. Two hundred and fourteen million.

Their share of the nation’s income has doubled since 1995. And the tax bill of our happy gazillionaires? Well, it’s fallen by almost half in that same period, from 30 to 18 percent.

Compare that against yours, and the national deficit.
