USA tycoons

 Los 400 estadounidenses que atesoran mayores riquezas poseen una fortuna colectiva ligeramente superior a la de la economía Rusa. Me abstengo de hacer comparaciones con otros territorios que presuntamente disfrutar de un "estado de bienestar". Y ni mencionar el resto del planeta. Los datos son de Forbes.

Bill Gates

"A record $2.02 trillion (£1.4tn), up from $1.7tn in 2012, a collective fortune slightly bigger than Russia's economy. In another sign of fizziness at the top of the economy, the cost to enter the billionaires' club has also gone up to levels not seen since the 2008 crash. In 2013, an aspiring plutocrat needs at least $1.3bn to make the Forbes list – the highest since just before the collapse of Lehman Brothers sent stock markets plummeting.

Bill Gates has been named as the richest American for the 20th year in a row, with a personal fortune of $72bn. The computer entrepreneur turned philanthropist recovered his position as the world's richest man in May, when he overtook mobile phone tycoon Carlos Slim, who had held the top spot for the previous four years.

Gates, the university drop-outwho founded Microsoft and has given away $28bn since 1994, saw his fortune grow by $6bn since 2012, partly helped by a rise in Microsoft's stock price since August.

In second place is Warren Buffett, the investor feted for his shrewdness, who recently bought Heinz. Buffett, with a fortune of $58.5bn, was one of the biggest gainers in 2013, which helped him retain his place on the list. The outspoken founder of software company Oracle, Larry Ellison, takes third place with a $41bn fortune.

The richest woman in the US, and the world, is Christy Walton, who inherited a retail fortune when her husband died in 2005. Walton is estimated to be worth $35.4bn, thanks to her shares in the world's largest supermarket Walmart, which has annual sales of $466bn and employs 2.2 million people worldwide – a workforce bigger than the population of Slovenia. She shares the Walmart fortune with her brother-in law Jim and sister in law Alice, who take sixth and seventh place on the list, with around $33bn each.

Facebook founder Mark Zuckerberg edged into the top 20 after his personal fortune doubled to $19bnas the tech company's stock price revived over the summer, following a wobbly stock market debut in 2012".( Extracto procedente de The Guardian by Jennifer Rankin, London)
