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.

We're diversified, we're stable and consistent. Our businesses benefit from each other.

I am struck that so many of our leaders in the U.S. forget how strong our country can be.

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.

The economic union - creating a big common market, like the United States, so that you can compete across borders. There are common rules, regulations, and simplification, and that is still a good reason, too. When they put their monetary union together, that created a rigidity that made it hard for currency fluctuations. They don't really have a solution to that.

Economies of scale are a good thing. If we didn't have them, we'd still be living in tents and eating buffalo.

I speak to lots of people around the world, and no one would tell you that 25 basis points will make a difference to them.
