[Donald] Trump has been very inconsistent on many things; on Twitter he's been all over the place, but some of it is very consistent. That is: Do nothing about climate change except make it worse. And he's not just speaking for himself, but for the whole Republican Party, the whole leadership. It's already had impact, it will have worse impact.

After World War II there were many Jews who remained in refugee camps...President Harry F. Truman called for the Harrison Commission to investigate the situation in the camps and it was a pretty gloomy report. There were very few Jews admitted into the United States.

Orwell says straight, look, in England what comes out in a free country is not very different from this totalitarian monster that I'm describing in the book. It's more or less the same. How come in a free country? He has two sentences, which are pretty accurate. One, he says, the press is owned by wealthy men who have every reason not to want certain ideas to be expressed. And second - and I think this is much more important - a good education instills in you the intuitive understanding that there are certain things it just wouldn't do to say.

The U.S. is, to a very unusual extent, a business-run society.

Caterpillar was quite important because that was the first manufacturing industry that used Reaganite strike-breaking techniques. They illegally called in scabs to break a major strike. It was reported pretty well in the Chicago Tribune, who pointed out something very interesting. They said that the workers got very little support in Peoria when scabs illegally broke the strike, and that was particularly striking because that whole community had been built up by the union - it was a union-based community.

I have never suggested any principled difference between the natural and social sciences.

Trump's principal policies make clear what's going to happen. This gives an opportunity. Right now it's going to take hard work, but it's possible that there could be a real revival of the labor movement.
