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

Their [American banks] big issue will be if they want to deal with the biggest companies, which are doing a lot of business overseas. How they do that is a big question. It's almost impossible to build a global investment bank from scratch. If they want to do that, they probably will have to do an acquisition.

When the government gets involved in pricing, I don't think it's the right way to look at a business.

If the numbers are right, ICBC [Industrial & Commercial Bank of China], which already earns nearly twice as much as JPMorgan. They'll probably be going a lot faster over time, and one day they can be a lot bigger than us.

Part of the concept of the euro zone was to establish a common market. The banks were going to bank across all their countries like we bank across states. But that concept got killed for a whole bunch of reasons that I won't get into. That was a good concept, by the way. It may yet return, because there are huge economies of scale in banking. That's another thing people don't quite get.
