24. Jimmy Buffett ($400 million)
Just thinking about the hit song “Cheeseburger in Paradise” makes us hungry. And you have singer, writer and businessman Jimmy Buffett to thank for that. A man who can best be described as a “jack of all trades,” Buffett is known for the Margaritaville restaurant chain and clothing line. He also famously made audiences laugh across the globe when he refused to relinquish his margaritas during a dinosaur attack during Jurassic World.
