The wealthiest Americans got even wealthier in 2013, by a lot. The 2013 Forbes 400 List, released Monday, found that the 400 richest US citizens increased their combined net worth to $2.02 trillion this year, up $300 billion from 1.7 trillion in 2012. That’s an all-time record, and, according to Forbes, is about the same as the gross domestic product of Russia. The minimum net worth needed to make the Forbes 400 list was $1.3 billion -- the highest since 2008 and a figure that kept 61 American billionaires off the list entirely.
... Microsoft founder Bill Gates was the richest person in America for the 20th straight year, a year in which he also reclaimed the title of the world’s wealthiest man from Mexican tycoon Carlos Slim. His net worth is $72 billion, according to the list. Behind Gates, once again, was Warren Buffet, chairman of Berkshire Hathaway. His net worth is listed at $58.5 billion, and he had the single-biggest dollar gain of anyone on the list -- $12.5 billion. Oracle founder Larry Ellison was third with $41 billion, and the Koch brothers, Charles and David, tied for fourth. Spots six through nine belonged to the Waltons, heirs to the Wal-Mart fortune. New York City Mayor Michael Bloomberg rounded out the top 10.
