The world’s new richest man, Mexican Carlos Slim, and a fresh crop of billionaires in Asia helped lead a comeback for the wealthiest few on the planet in 2010, Forbes magazine said Wednesday.

The publication’s annual rich list reflected a resurgence of wealth after the financial turmoil of 2009, with the top 10 wealthiest worth a combined 342 billion dollars, compared to 254 billion dollars in the previous year.

“The global economy is recovering. The financial markets came back, especially emerging markets,” said magazine editor-in-chief Steve Forbes.

“There’s a 50 percent increase in general global wealth compared to last year,” Forbes said.

Certainly the economy recovered for the super rich, who took a beating during last year’s stock and commodity market collapses, but saw across-the-board gains this year.

Forbes counted 1,011 billionaires from 55 countries, up from 793 last year, though still shy of the pre-crisis 1,125 listed in 2008.

The top 10 richest people in the world have a combined worth of 342 billion dollars in 2010, up from 254 billion a year ago.
