With an estimated net worth of $74 billion (yup, BILLION) dollars, Carlos Slim Helu has a firm grip on first place of Forbes list of the World's Richest People. Holding on the to the top spot for the second year in a row, Helu managed to add $20.5 billion to his fortune—increasing the gap between him and no. 2, Microsoft cofounder Bill Gates, to $18 billion.
Two Latinos were also featured on the World's Youngest Billionaires list. Facebook cofounder Eduardo Saverin clocked in with a net worth of about $1.6 billion. After a now infamous fight with former business partner Mark Zuckerberg that led to a best-selling book and spawned an Oscar-nominated Hollywood film (The Social Network), 29-year-old Saverin settled out of court for a reported 5% share in the company and a cofounder bio on the site.
37-year-old Ana Lucia de Mattos Barretto Villela was also featured on the youngest billionaires round up. With a net worth of 43.2 billion, she is a very low-profile member of one of Brazil's most distinguished families. Barretto Villela is also one of the largest individual shareholders of Itau Unibanco Holding SA (Brazil's second biggest bank and one of the world's 15 largest). She is currently the president of the Alana Institute, a nonprofit with the mission of promoting social work, education and culture.
