There are 40 billionaires who've currently pledged to participate -- including one George Lucas. The film mogul often gets a bad rap from fans for ruining Star Wars with bad spin-offs and "revised" re-releases -- and we've all made jokes about him rolling around on beds covered with cash -- but this is a really great gesture on his part. See? Maybe all that money you spent on The Phantom Menace and Star Wars action figures and collectibles did serve a greater purpose. Take that, Mom!
Lucas joins other notable rich folk like Gates, Buffett, Oracle co-founder Larry Ellison, T. Boone Pickens, and more on the list. The Giving Pledge isn't a binding contract, and participants can freely donate more than 50% of their wealth if they choose (Buffett has pledged 99% of his -- hear that? it's the sound of his heirs groaning ... ) and can decide where it goes. Still, sounds like a nice gesture. Let's all remember this next time we're complaining about Lucas milking his franchises -- clearly he's just doing it so he has more money to give away one day.
