In 2009, the two richest men in America organized a confidential dinner meeting of billionaires in New York City, hosted by David Rockefeller. Guests included George Soros, Michael Bloomberg, Ted Turner, and Oprah Winfrey. The topic of discussion was philanthropy. Each billionaire was asked to describe his philosophy of giving. CNN-founder Ted Turner told the story tale of how he had made a spur-of-the-moment decision to donate $1 billion, most of his future, to the United Nations. During this dinner, Bill Gates and Warren Buffet started the biggest fundraising drive in history. Setting examples though their own charity, Gates and Buffet initiated “The Giving Pledge”, a campaign encouraging billionaires to commit the majority of their wealth to philanthropic causes. So far around 113 billionaires have agreed to the pledge.
