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 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.

I really do put it on Bill Clinton's presidency as the time when the Democrats became the party of the college degree as the key to success in life.

I think that bias is not a fixed thing. It's not as though some people are biased and others are not. It ebbs and flows. It can be manipulated. It changes according to a person's circumstances.

The literature of the Spanish Civil War is also important to me. Above all George Orwell's "Homage to Catalonia" as well as the writing of John Dos Passos and Ernest Hemingway. They worked on a film together in Spain during that war, which ended their friendship.

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.

Since I was a kid. I had this series by Ballantine Books about the history of World Wars I and II. In my 20s, it was the Vietnam War literature of novelists like Tim O'Brien, Philip Caputo, and Tobias Wolff, and then nonfiction such as "A Bright Shining Lie" by Neil Sheehan and "The Best and Brightest" by David Halberstam . Those are the two best histories of Vietnam.
