Chuck Feeney joined the ranks of billionaires who have given it (mostly) all away. The act is called The Pledge and began with Warren Buffett. In 2009, after donating billions of dollars to charity, Buffett was ranked as the second richest man in the United States with a net worth of US$37 billion with only Bill Gates ranked higher than Buffett. His net worth had risen to $58.5 billion as of September 2013. At the Pledge he has put himself down for giving away 99% of his money in the years to come. Bill Gates and his wife Melinda have done the same. 
Today I learned former billionaire Chuck Feeney has given away over 99% of his 6.3 Billion dollars to help under privileged kids go to college. He is now worth $2 million dollars.
