Mr. Vincent, you said there's no study of a system with no regulation. Well, we do have, currently, no regulation. We have our experience of the last 30 or 40 years. In the last 30 or 40 years, interchange fees have not changed at all. The nature has changed, but the average interchange fee is the same.
You talk about interchange. How do we know that it won't go up? It's stayed the same, and it's stayed the same because it's set to balance the system. Visa doesn't make more money by charging more interchange fees. It's done in order to take account of the fact that they want to provide the correct incentives to the card issuers. If it went to 10%, they would not make one cent more.
