A majority of Americans support Social Security and Medicare, a progressive tax system and a government that regulates business in the public interest, but most share deep skepticism about the government's ability to do all this well.

There is such a polarized discussion of economics among people like analysts, columnists, bloggers; often, they end up just saying that views other than their own should not even be discussed. I find that frustrating. There is no intellectual progress without considering lots and lots of different views.

To put it simply and a bit crudely: Our economy is demanding more well-educated workers than our schools are providing. To attract this scarce resource, communities have to offer more than just jobs.

I don't think that much change comes from economists. I think it comes more from political realities. Probably the two giants of the 20th century, who actually did shift government policy in the U.S. and around the world, were John Maynard Keynes and Milton Friedman. I don't see anybody in our system who is at that level of influence.

The cardinal rule of taxation is that whatever you put a levy on, you'll inevitably get less of. Taxing corporate activity means less investing, less hiring, fewer jobs and a smaller economy, which hurts the rich, the poor and the middle class alike.

'The Old Social Classes and the Revolutionary Movement in Iraq,' by Hanna Batatu. Few may wish to take on this massive, obscure work, but it changed my life, and I love it.

'Reinventing the Bazaar,' by John McMillan, is a great and fun introduction to the wild variety and importance of markets throughout history and around the world. I finally understood how a Middle Eastern souk actually works economically and how to compare that to modern-day telecom-spectrum auctions. I love that book.

Hating Wall Street is an American tradition that dates back even to the days when Thomas Jefferson cursed that money lover Alexander Hamilton. And for centuries, the complaints about it have largely stayed the same: 'It does nothing! It creates chaos! It's a parasite that sucks hardworking Americans dry!'
