I just think, realistically, there's a lot of room outside the Trump populist right and the Bernie-Sanders-Elizabeth-Warren populist left. There are a lot of us who believe in open trade, open borders, a dynamic forward-looking economy, not a nostalgic economy, but do want to provide a significant level of social service or sort of economic Milton Friedman foreign policy, Ronald Reagan domestic policy, Franklin Roosevelt. And there's a lot of room in the center.

I think the twenty-first century happened, basically. That this century started on 9/11. And basically, it's been a century of counter reaction to globalization and the meritocracy. And a good century for 72 nations have gotten more authoritarian. We've had Brexit. We have Le Pen rising in France. We've just got a lot of these types all around the world. And the people who are suffering from globalization and the meritocracy are saying, "No more. You know, we get a voice too."

Economists sometimes do try to reduce behavior to law-like predictability. But people respond differently to different primes, to different contexts even from one moment to the next. We possess multiple selves that are aroused by different circumstances.

Donald Trump is this whirling dervish of chaos. He picked a fight with Mexico. Germany is not far behind. He will pick a fight with them. He will pick a fight with China, which would be truly cataclysmic.

I happen to think most people go into government do it for the right reasons and they really do things as they see them on the merits of the issues.

On the [Andrew] Puzder point, I do agree there has been a double standard.

Benjamin Netanyahu is a fascinating figure.We say Nixonian about a lot of people. He really is Nixonian. He's brilliant. He's very isolated and insular.
