Everything has to be done to build some sort of international democracy. We've seen only the tiniest beginnings of that.

I think the market is always going to be around. The goal is not to say, let's get rid of the market, because the market does render a huge number of services, and I don't want to have a fight about the price of something every time I buy a book or a bottle of water.

This erosion of the middle class is happening all over the place. The opening of a wider gap between rich and poor is always accompanied by such a process.

Having enough to eat, being able to educate your children, have reasonably stable employment, and being able to live in a society which isn't collapsing around you-all of these things have been generally eroded.

I used to work a lot on food issues and every time somebody predicted that production would be inadequate they got egg on their face a year or two later.

The real fight is about what should be in the marketplace and what should not. Should education be a marketable commodity? Should healthcare?

The question is not only what is grown but what it's used for. There's not going to be a mass transformation of dietary habits in rich countries-on the contrary, the first thing people do when they become more prosperous is to buy more meat.
