Zuckerberg & other US billionaires join Buffet to give their millions to people

Mark Zuckerberg and Dustin Moskovitz joined the list of US billionaires who have pledged to give away at least half their fortunes in a philanthropic campaign led by Warren Buffett and Bill Gates. To date a total of 57 billionaires have joined The Giving Pledge, which was launched by Microsoft founder Gates and investor Buffett in June. The campaign announced the new pledges in a statement late on Wednesday.

While the Giving Pledge accepts no money, neither it tells them how to donate their money, Gates, his wife Melinda, and Buffett have asked U.S. billionaires to give away at least half their wealth during their lifetime or after their death, and to publicly state their intention with a letter explaining their decision.

"People wait until late in their career to give back. But why wait when there is so much to be done?" Zuckerberg, who gave $100 million in September to the beleaguered public schools of Newark, New Jersey, said in a statement.

"With a generation of younger folks who have thrived on the success of their companies, there is a big opportunity for many of us to give back earlier in our lifetime and see the impact of our philanthropic efforts," he said.

In addition to Zuckerberg and Moskovitz, the world's youngest billionaires, pledges were made by AOL co-founder Steve Case, financier Carl Icahn and Michael Milken, a former Wall Street executive who went to prison in the early 1990s for securities violations.

Morningstar Chief Executive Joe Mansueto, businessman Nicolas Berggruen and private investor Ted Forstmann also are among the new billionaires to take the pledges.

"In just a few short months we've made good progress," said Buffett, who made his fortune with insurance and investment company Berkshire Hathaway Inc.

"The Giving Pledge has re-energized people thinking about philanthropy and doing things in philanthropy and I look forward to many more conversations with families who are truly fortunate and whose generosity can and will change lives," he said.
