Mexico’s Carlos Richest Man on Earth

Microsoft’s founder Bill Gates isn’t the richest man on earth anymore. Mexico’s tycoon Carlos Slim Helu has overtaken Bill Gates with 67.84billion of fortune. Carlos has a great influence over the telecommunications industry in Mexico. Earlier in April, he is 3 billion behind of Bill Gates. But just after months later, he has rapidly gained ahead of Bill Gates. This is because of the 27% surge of his cellphone operating business in America Movil.
 
I still wonder how he manage to surpass those billionaires like Warren Buffett, Paul Allen, George Lindemann and etc.
