Being captive to quarterly earnings isn't consistent with long-term value creation. This pressure and the short term focus of equity markets make it difficult for a public company to invest for long-term success, and tend to force company leaders to sacrifice long-term results to protect current earnings.

How do we make people's lives better unless we find the truth of what works and what doesn't?

I think this is so important - what's not done well at education at every level - is helping kids find, as I discovered for myself, what I was good at. I was very lucky to find out that at an early age, which set my direction in life.

A university shouldn't be a place of comfort. It should be a place of discomfort because you want to disabuse these kids of whatever prejudices or preconceptions they have when they come. You're trying to get them to think and develop, not be a Johnny-one-note.

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.

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.

Most companies want free enterprise in general because that produces better goods and services and makes people's lives better, but they don't want it in their business. They want protection from competition, they want subsidies, they want the government to pick winners and losers, and they want to be picked as winners, and that's what we're opposing, and that's what drives my whole efforts in policy, and in the political arena.
