As the U.S. national debt continues to increase, billionaire Douglas Durst, whose father Seymour put up the National Debt Clock in Times Square in 1989, believes the solution is for the government to collect more money. "I think America has more of a revenue problem than a spending problem," he recently told The Washington Post.

His suggested remedy: Ask for more from the rich. "I support higher taxes on people like me," he says.
