Steve Wozniak interviewed for CBS:

"I gave all my Apple wealth away because wealth and power are not what I live for. I have a lot of fun and happiness. I funded a lot of important museums and arts groups [...] I never look for any type of tax dodge. I earn money from my labor and pay something like 55% combined tax on it. Life to me was never about accomplishment, but about Happiness. I developed these philosophies when I was 18-20 years old and I never sold out."

He turned 75 4 days ago.
