That would be nice if [people] stuck [treasury bills] all under a mattress, but they got to buy something with them. Sometimes they buy a treasury note, sometimes they set up sovereign wealth funds. They can do all kinds of things. They can buy our companies here. As long as we consume more than we produce, and we trade away little pieces of the country daily, they're going to own something.

We have to live with the rest of the world. And it's a mistake, in my view. Trade has generally developed in this country. We actually export 12 or 13 percent of our GDP. It was only 5 percent in 1970. But it benefits us. It benefits the rest of the world. It doesn't benefit the steelworker maybe in Ohio. And that's the problem that has to be addressed, because when you have something that's good for society, but terribly harmful for given individuals, we have got to make sure those individuals are taken care of.

It's class warfare, my class is winning, but they shouldn't be.
