Quotes 1990s, 1995-1999, Sovereignty and World Order, 1999
Context: I should say that when people talk about capitalism it's a bit of a joke. There's no such thing. No country, no business class, has ever been willing to subject itself to the free market, free market discipline. Free markets are for others. Like, the Third World is the Third World because they had free markets rammed down their throat. Meanwhile, the enlightened states, England, the United States, others, resorted to massive state intervention to protect private power, and still do. That's right up to the present. I mean, the Reagan administration for example was the most protectionist in post-war American history. Virtually the entire dynamic economy in the United States is based crucially on state initiative and intervention: computers, the internet, telecommunication, automation, pharmaceutical, you just name it. Run through it, and you find massive ripoffs of the public, meaning, a system in which under one guise or another the public pays the costs and takes the risks, and profit is privatized. That's very remote from a free market. Free market is like what India had to suffer for a couple hundred years, and most of the rest of the Third World.

Interviewed in the documentary series The Civil War, 1990
Context: Any understanding of this nation has to be based, and I mean really based, on an understanding of the Civil War. I believe that firmly. It defined us. The Revolution did what it did. Our involvement in European wars, beginning with the First World War, did what it did. But the Civil War defined us as what we are and it opened us to being what we became, good and bad things. And it is very necessary, if you are going to understand the American character in the twentieth century, to learn about this enormous catastrophe of the mid-nineteenth century. It was the crossroads of our being, and it was a hell of a crossroads.
