Forbes has it's annual World's billionaires list out which places Warren Buffet on top beating Bill Gates, and that Mexican guy, who supposedly overtook him. The Indians are catching up too, from the WSJ:

the biggest surprise is the rise of the Indian rich — four of the top eight billionaires in the world are from India. Topping the ranks is steel tycoon Lakshmi Mittal, whose worth Forbes puts at $45 billion. Next up are the Ambani brothers, Mukesh and Anil, with $43 billion and $42 billion respectively, largely from petrochemicals. Rounding out the list is KP Singh, the real-estate magnate, at $30 billion.

[..]a greater and greater share of the world’s millionaires and billionaires will come from India, China, Brazil, and Russia. That’s not to say the U.S. won’t keep producing rich people of its own. Rather, it’s that the most rapid growth, and the billionaire “market share,” will move to emerging markets. [link]

Mark Zuckerberg, the founder of Facebook, is the youngest billionaire, at 23 years of age. I wonder when will the first Sri Lankan enter the list, maybe Mahinda has a chance. He'll own most of the country before he leaves office.
