I went to Northwestern in Chicago, in Evanston, and then I ended up trickling down in Chicago theater. I did a bunch of plays, but I was non-equity. For a lot of people, non-equity means you're not yet professional. But for me, if you're in a mainstream theater, you're doing something real.

Leverage is great when it works, and when it doesn't work, it creates a lot of issues. So I think if you limit the amount of leverage that people can borrow, or that banks can borrow, I think you'll find that you'll have a lot less issues going forward.
