I don't think you could have a banker serving in a major role in Washington in the next 10 years. I just don't think it's going to happen - it's just not politically feasible - so I don't spend much time thinking about it. Do I think I could do a good job? Maybe. It's possible.

Companies that build scale for the benefit of their customers and shareholders more often succeed over time.

If the economy grows, housing gets better, quicker.

There are parts [in Dodd-Frank] that I don't agree with. But, in total, it is what it is.

And if you're going to be a leader, you know what I ask myself? Would I want to work for you in this job? Would I let my children work for you? Would I give you this job if I wasn't there to provide oversight? If you went to run another company, would I, as an investor, invest in that company?

I also think you have to be very careful. I mean, the heritage of our company is very strong, and building some of these businesses into leading players is extremely tough. You and I can both build a trading business, and it looks like you're doing OK, and it looks like I'm doing OK. But, really, I am, and you aren't. It comes down to the quality of clients, quality of systems, quality of risk controls.

Just because you have a good hand today doesn't mean it's good tomorrow. And some of the things we're doing may become very disadvantageous at some point.
