Back in 2006, the high-profile lawyer's wife celebrated Boies' 65th by flying friends on two chartered jets to Las Vegas for a weekend at Steve Wynn's casino, courtesy of Boies' hauls from cases for representing clients from George Steinbrenner to Al Gore in the recall aftermath of the 2000 presidential election. Attendees regaled media at the time with anecdotes such as a wine tasting on the planes.

This year, Boies celebrated his 70th birthday by again flying friends to Las Vegas-- though he may have cut the guest list down to only one plane. Tightening the belt on such celebrations is not how billionaires roll, says Marto, who adds that the billionaire party business is down only 10-15% from its 2008 peak. "They typically go ahead and do what they want to do," he says. "They still have the money to do it."
