It's no secret that the U.S. is going through some tough times. With nearly 10% of Americans out of work, most people are just trying to make ends meet - these are definitely not those people. Bill Gates and Warren Buffet are of course at the top of the list, despite Buffet's $6 billion loss this year.
There are also some fresh, young entrepreneurs giving the seasoned vets a run for their money. Facebook founder, Mark Zuckerberg rounded out the year with a net worth of $17.5 billion, making the top 20 for the first time. He slid in just ahead of Sergey Brin and Larry Page, Google's co-founders, who fell to number 15. Wondering who the rest of the top 10 might be and how they've accumulated their wealth?
