Bill Gates says that Wall Street executives often get paid too much. In his remarks made in New York City, Microsoft co-founder Bill Gates said that executive pay is "often too high." But the multi-billionaire also cautioned against controlling executive salaries, citing the 1993 U.S. law that capped exec salaries at $1 million as "a bad milestone," Reuters reports. "The compensation problem is a very interesting problem. I do think compensation is often too high, but it's a very tough problem to solve," said Gates. Forbes recently placed Gates' wealth at $40 billion, despite losing an estimated $18 billion over past 12 months.
