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.

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.

If you talk to anyone involved in business - forget banks and big business - talk to small businesses - do it yourself, don't ask me - they'll tell you it's crippling. Small-business formation is the lowest it has ever been in a recovery, and it's really for two reasons. One is regulations and the second is access to capital for people starting new businesses.

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.

It's hard in all countries. Democracy is hard, but it's better than the alternatives.

Usually, something that is fairly expected is already factored in. I also think that you have to think that America is raising rates because the economy is getting stronger.

Good regulation should be conducive to business and to customer protection.
