Frederick Soddy

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.

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.
