TIME interview (1991)
Context: I don't think we're ever going to have a cheap fascism of Brownshirts and goose stepping or anything of that sort. We're too American for that. We would find that ridiculous.
But there are always traces of repression. And you can find it in a Democratic government too. People who are "right-minded," you know, are always with us. But I think so long as we can move along with the economy, we're all right. It's just if there's a smash, a crash — that's when I'm not at all optimistic about what's going to happen.
