Exporters monitor economic and political policies to the developing world, but the consequences of that have been to make developing countries far more sensitive to the constant fluctuations. Developing countries are not always allowed to support their farmers in the same way as the U.S. or Europe is. They're not allowed to have tariff barriers. They're forced, more or less, to shrink their social programs. The very poorest people have fewer and fewer entitlements. The consequence of this has been that there's been a chronic increase in the vulnerability of those economies to price shocks.

India has the largest number of hungry people. Yet it's an outcome of precisely the same mechanism. It's the control of agriculture that drives down the price it paid for food that it buys from farmers, who are the poorest people. Then you're paying very little for food. You're underpaying the poorest people in any society. Then they're marketing to us the things that are most profitable to them. And those are the things that are packaged and processed and what-have-you. That means you have the simple thing of the explosion of obesity and hunger as a result of capitalism in our food system.

We have the industrial agriculturalists who try and make an argument that big is beautiful. But if you do the math, and particularly if you factor in that the price of oil is going to go through the roof, and so the price of transportation is going to go through the roof - making it abundantly clear that it's out of whack. The efficiency arguments are already crumbling, particularly if you actually include the cost of food pollution that these industries cause. They are tremendously unsustainable and tremendously inefficient.

All of human history is about the going from sudden fat years to the sudden lean years. We've always had good times and bad, and we've had ways of managing the bad times. We have ways of insulating ourselves, making ourselves less sensitive for the bad times by having things like grain stores, for example. Pretty much every civilization that's lasted for any reasonable length of time has some food management principles behind it. But what's been happening over the past thirty years is it's failed - the insurance policy.

One of the most abused country on earth is Mexico. The marketing spills over the border, and people are persuaded to eat food that's bad for them, more in rich countries than in poor ones. I was traveling the world. What really struck me was the way we engage with food - how it's a global phenomenon - the world becoming more and more disconnected from it.

The one thing that everyone knows about America is people will say, I know my rights. One of those rights is the right to organize. When workers do get together and organize and drive up their wages, they are much, much better off. I think this is one integral part of food policy. We can't talk about increasing the price of food without figuring out how working Americans are going to pay for that.

I definitely think the price of food is going up. We need to figure out ways to manage that in a sustainable way. We have to figure out ways of increasing wages so people can afford it. That means redistribution, and rich people don't like to hear that. This administration simply won't hear of it. But without it, I fear even more Americans will be going hungry in the future.
