The richest man in the world added $20.5 billion to his net worth over 2010, raising the total to an estimated $74 billion, according to the annual Forbes rich list. Telemex Chairman Carlos Slim Helu surpassed No. 2 rich-man Bill Gates in wealth in 2009, and has now extended his lead by $18 billion. According to Forbes, "A 19 percent rise in the Mexican stock market, a stronger peso, and successful mining and real estate spinoffs from conglomerate Grupo Carso all contributed to the astonishing increase." Mr. Slim also has stakes in retailer Saks and The New York Times.
But when it comes to power, Slim still lags behind the Microsoft founder. Forbes ranks Slim No. 20 on its "Powerful People" list, 10 spots behind Mr. Gates.
