Warren Buffett and Bill Gates called him their hero. He owned no car, no house, one pair of shoes and a $15 watch. He flew economy and carried his papers in a plastic bag. His name was Chuck Feeney, he built the biggest duty free empire on earth, and the reason he lived like that was a piece of paper he signed in 1982. That was the decade of greed. I was on the Street that year, and everyone I knew was counting the bonus they hadn't been paid yet. Feeney was quietly sitting with his lawyer, about to sign his entire fortune over to a foundation. Not most of it. All of it, after a modest provision for his family. The lawyer did his job. He told him three times. Once this is done, it's gone. If you change your mind three days later, you can't get it back. If you think you've made a mistake, you can't get it back. Feeney was impatient with the warning. His answer was, let's get on with it. Nobody knew. The press didn't know, and even his own family had no idea what he was worth. He kept running the business, and every dollar of profit went straight out the door. Over four decades he gave away more than $8 billion. When he died in 2023, he had less than $2 million left. Exactly as planned. No pledge, no press conference, no deathbed. He did it without a second thought because he wanted to and believed it was right. Every billionaire who promises to give it all away after he's gone isn't being generous. He's keeping the money and asking someone else to do the hard part.
