In the Futurama episode "A Fishful of Dollars" Fry becomes a billionaire because he had a bank account 1000 years ago and made interest on the small amount of money he had in it. Fry seems to be the only person to have done that, but we know that many other people froze themselves and got sent into the future. Isn't it likely that they too would have had bank accounts during their time, and they too would have become billionaires? And the mere fact that it is possible seems like a major flaw, because people who never worked for their money (Fry) could still make billions of dollars.
Were there any other people that froze themselves and become billionaires like Fry?
