I think normalization is a good thing.

The question is how do you do it [more consumer protection] so that it actually works that way? And that takes analysis, and sometimes collaboration between government and business, to understand how that works.

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.

The best way to look at any business is from the standpoint of the clients. So there are these certain basic things that aren't going to change. Companies are going to have needs for equity, debt, advice, FX, and derivatives. Individuals are going to have needs for auto loans, mortgages, something that looks like a deposit account, and the ability to send money to people. Those things aren't going to change.

I don't like the term "universal bank." The Chinese government legitimately wants to have a very strong economy. When they talk about SOE reform, they know that's part of it.

We, Americans, have the best country on the planet. We have schools, universities, food, water, energy, peaceful neighbors, low corruption, you name it, deepest and widest capital markets. That doesn't mean we shouldn't identify problems. We don't have a divine right to success.

You've seen certain credit type products that are going to be in nonbanks, like sophisticated CLO [collateralized loan obligation] tranches and stuff where the capital charge is so high that a bank simply will not own it. Someone will buy it, hedge it, trade it. But it won't typically be a bank.
