If you look at Detroit, that mayor, it's been a train wreck for 40 years, the population has gone from 2 million to 700,000. This Mayor comes in, and he talked about streetlights, sanitation, jobs, policing, schools, affordable housing. He's doing it all, and it's growing for the first time in 30 years. Literally, one man. But that one man couldn't do it without business. And business couldn't have done it without a political environment where they wanted to improve things. If you had an antibusiness environment there, it would still be down there.

Businesses can be opaque. They are complex. You don't know how aircraft engines work either.

Prime Minister Modi [Narendra] is strong enough, and he's accomplished much.

You never know exactly how new policies are going to work. That doesn't mean you shouldn't try them.

The toughest are people mistakes, when you put the wrong person in a job. Sometimes you're too slow to move them out. Or not getting the right people involved to solve a problem, or doing something out of anger; you learn, just don't do that. But I'd have to say the Whale was one of them, and I would also have to put Bear Stearns and Washington Mutual on the list at this point.

If business doesn't thrive, it hurts America. We need improved relations, more collaboration, more thought and more consistency as we go about trying to make sure we have the best country in the world. Not scapegoating and finger-pointing.
