#3. Jeff Bezos
Thanks to a business that was started in his garage in 1994, on a whim carried by a statistic about the internet, Mr. Bezos now has a net worth of $66.5 billion. Despite the massive size and success of Amazon, he likes to keep himself busy with his two other companies he manages. Blue Origin, which is an all American privately funded aerospace manufacturer and spaceflight services company, he also manages The Washington Post, which is a well-known successful magazine.
