Any society has to delegate the responsibility to maintain a certain kind of order. Enforcing regulations, making sure people stop at stoplights. We can’t function as a society without rules and regulations, and the enforcement mechanism of those rules and regulations.

One has to always ask the question: Where can one be most effective in helping shape policies? It is always difficult when you're inside because you're very constrained.

It's actually a tribute to the quality of economics teaching that they have persuaded so many generations of students to believe in so much that seems so counter to what the world is like. Many of the things that I'm going to describe make so much more common sense than these notions that seem counter to what one's eyes see every day.

The fact that the government had to put up hundreds of billions of dollars to Citibank in guarantees was a public declaration that Citibank was a mess. Making Citibank go through financial restructuring would not have conveyed any more different information. So it's very hard to see why it would have had that kind of a panic if it were done well.

There have always been two theories about inequality. One is that it reflects just deserts. The other is that there are large elements of exploitation and inequality of opportunities. The evidence is overwhelmingly that the increase in inequality is associated with those negative factors. If it were all social contribution, then when the top did better, they would be contributing to everybody's well-being. That trickle-down hasn't happened. We've seen median income, people in the middle, actually worse off than they were 25 years ago.

The war in Iraq has been very, very expensive - partly because the Administration tried to keep the apparent costs down. But the benefits have been elusive at best - partly because the ostensible reasons for going war were unconnected with reality - no weapons of mass destruction, no connections with 9/11.

For that to happen, growth has to be very strong. To get back to normalcy, we will have to have extended growth of more than 3 percent. That's not in the cards.
