The five richest men in the US are worth a mind-boggling combined $US435.4 billion, according to the Forbes 400 ranking of 2019’s richest Americans. And all but one of them made their fortunes in the tech industry.

Amazon CEO Jeff Bezos tops the list with a net worth of $US114 billion, followed by Microsoft co-founder Bill Gates ($US106 billion), investor and Berkshire Hathaway chairman Warren Buffett ($US80.8 billion), Facebook CEO Mark Zuckerberg ($US69.6 billion), and Oracle co-founder Larry Ellison ($US65 billion), according to the Forbes ranking.

Their combined fortune comes out to more than 2% of the US GDP, which was $US21.34 trillion in the second quarter of 2019. (Exactly 2% of $US21.34 trillion would be $US426.8 billion.)

A Business Insider analysis found that for a billionaire, buying a vacation to Bali is the equivalent of a typical American buying a candy bar. And that’s based on a net worth of just $US2 billion, the median fortune of a Forbes list billionaire.

While these five men are the richest in the US, one European billionaire knocks Ellison off the list of five richest men in the world. Bernard Arnault, the French businessman who controls LVMH, is worth $US91.9 billion, making him the third-richest person in the world after Bezos and Gates, according to Bloomberg’s Billionaires Index. Forbes estimates his net worth at a slightly lower $US91.4 billion, still well above Zuckerberg and Ellison.

The US is the world’s dominant country for billionaires, home to an estimated 705 billionaires, as Business Insider’s Hillary Hoffower previously reported. New York City, San Francisco, and Los Angeles have the highest concentration of billionaires in the country.

China comes in second place, with 285 billionaires, but it may be catching up to the US. According to a recent PBS report, China is producing billionaires at a faster rate than any other country.
