This guy is my hero. I do hope he was able to enjoy spending some of his money on himself and his family though. I have no problem with billionaires who contribute a lot to society living well as long as they aren't hording resources (huge acreage estates, mega yachts, rental properties). "Contribute to society" is the sticking point for many of them though.
I hope I can live like Mr. Feeney, although I personally wouldn't be quite as ascetic as he given the circumstances (I would own a small but nice house in San Diego or Hawaii and a nice 0 emission solar/sail powered boat).
Good work Chuck!
