Billionaire philanthropists Gates and Warren Buffett urged India's tycoons on Thursday to give up some of their newfound wealth to help the country's hundreds of millions of impoverished people. Last year, India's third-richest man, Premji, shifted shares worth about $1.95 billion in his software services giant Wipro Ltd. toward funding education for the poor. It was the country's largest lump-sum donation in modern times. (AP Photo/ Mustafa Quraishi)
