I want my books to last, to stand the test of time, and to do that I focus on the forces that shape the subject - the cultural and sociological geography - to capture them in a way that will explain them no matter what they are doing.

Well, there were several things. One was that the industry itself built in Detroit was abandoning the city - taking factories elsewhere, the corporate headquarters elsewhere.

I want to write for history, not for the moment.

And all of the big shots of the car industry are there, strutting their stuff. And that year, they're feeling especially good because cars were selling more than ever before.

My basic philosophy is that no human being is a saint.

So, I mean, there's still vast swaths of the city that are suffering from a lack of jobs and poor housing and poor public schools, but they are building momentum - you know, techies, foodies, artists, musicians, all coming to Detroit. So there is this vibrancy. You see it in the newspapers every day - some story about the new Detroit.

It was a time of uncommon possibility and freedom, when Detroit created wondrous and lasting things. But life can be luminescent when it is most vulnerable.

And then the industry itself was so cocky about what they were doing that they weren't seeing what was coming on the horizon with Japan and Germany and other places that were building smaller cars.

Natural politicians are skilled actors, recreating reality, adjusting and ad-libbing, synthesizing the scenes, saying the same thing over and over again and making it seem that theyare saying it for the first time.

Originally, John Kennedy was going to come speak, and then Lyndon Johnson. Because it was October of '62, neither made it because of the Cuban missile crisis.

Well, there is something beautiful about ruins. I mean, in one sense it's not that different from going to Rome and looking at the Forum. But it's changing. It truly is. I'm optimistic but skeptical.
