I will find any excuse to go into somebody's study or ask them what they are reading. I can't think of too many other things that say what goes on in someone's head than the books they have.

I think in the '50s, the percentage of Americans employed by the private sector who were in unions was above 30 percent. And now it's in the single digits, so it plummeted. And with the plummeting of unions came the weakening of an organized working-class voice in politics.

Hillary Clinton said we need to bring back vocational education in high school. We need to support community colleges. We need to make sure that people who are not going to finish college have a job waiting for them and the skills to do the job. These are all - have become fairly standard Democratic policy positions.

This is what Newt Gingrich has wrought - is a politics in which it's very easy to destroy and very hard to build.

Hillary Clinton would say I'm going to fund a program that will find the local, you know, industrial or manufacturing jobs that are available and train you to do that job. And then you're going to get that job. And it's a much more of a nuts and bolts sort of policy vision.

What goes on in a person's head, what impels them to a political choice, it's a pretty complicated question.

We will have a more just society as soon as we want one.
