The past few years have been very good to Stephen Schwarzman, the chairman and C.E.O. of the Blackstone Group, the giant private-equity firm. His industry, which relies on borrowed money, has benefitted from low interest rates, and the stock-market boom has given his firm great opportunities to cash out investments. Schwarzman is now worth more than ten billion dollars. You wouldn’t think he’d have much to complain about. But, to hear him tell it, he’s beset by a meddlesome, tax-happy government and a whiny, envious populace. He recently grumbled that the U.S. middle class has taken to “blaming wealthy people” for its problems. Previously, he has said that it might be good to raise income taxes on the poor so they had “skin in the game,” and that proposals to repeal the carried-interest tax loophole—from which he personally benefits—were akin to the German invasion of Poland.
