Bernie is, of course, not the first person to use this “my wealth good, your wealth bad” line while attacking other rich people.

During the Occupy Wall Street protests in 2011, Michael Moore posted a screed to his Web site defending his being in the 1 percent while railing against capitalism. No, you see, he didn’t make his money via capitalism. He made his money by making films and selling these — which is somehow completely different than how other capitalists do it. “I make my money the old school, honest way by making things,” he wrote with no hint of irony or introspection.

Closer to home, Mayor de Blasio likes to repeat that “the money is in the wrong hands.” The creepy refrain is often accompanied by the idea that the mayor knows exactly “where it is.”

We all know where it is: The mayor who owns a $2 million dollar house in Park Slope has it! This is the great promise of America: A guy who takes a motorcade to ­another borough to work out at his preferred gym has the gall to lecture the rest of us on being too wealthy. You can be anything in this great land, even a really rich guy criticizing other people for being rich.
