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.

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.
