Of all the bad press generated by Steve Schwarzman‘s recent 60th birthday party, the worst may be tucked within today’s Dealbook column in the New York Times in which Andrew Ross Sorkin takes on the highly-paid pirates of private equity. “It is a charade that private equity firms have claimed their 20 percent performance fees at the lower capital gains rate,” he writes. “To qualify, they invest a nominal amount of their own money to demonstrate that they have put something at risk, but it’s a ruse. They are paying capital gains rates for doing their job, which should be taxed at the regular income rate.” Will Steve serve White Castle at his 65th? Stay tuned.
