The role of business is to provide products and services that make people's live better - while using fewer resources - and to act lawfully and with integrity. Businesses that do this through voluntary exchanges not only benefit through increased profits, they bring better and more competitively priced goods and services to market. This creates a win-win situation customers and companies alike.

I've always believed in the saying that "there is no limit to what you can accomplish if you don't care who gets the credit."

In America, we are just moving the chairs around and spending huge amounts of money rather than having them go in making people's lives better.

I didn't think I was good at anything, didn't do well in school. And then in the third grade, I was going to a public school. And the teacher was putting math problems on the board. And I said to myself - it's amazing how you can remember certain incidents at any age that made an impression - I asked myself why is she putting those up when the answers are obvious. And then I saw it wasn't obvious to anybody else in the class. So I said, "Hey, I'm good at something."

I get a lot of death threats. But the way I look at it, I feel I have a moral obligation to do the best I can to make the country better for everybody, and that threatens certain people because they're going to have much less power. I want the power to go back to people making decisions over their own lives rather than some experts making it.

Hubris, arrogance, is just one step ahead of loss of integrity, because if you think you're better than other people, you know more, then you're going to think, as many leaders have, that the rules don't apply to them - so they lose their integrity.

Everything I give, pretty much, is public. Not every donor wants to - or is willing to get the kind of abuse and attacks that we do, or death threats, so they're not willing to have their names out. I think the other side is pushing for that because they want to intimidate people so they won't oppose it.
