Given that full disclosure is an issue, I should disclose that I did my Ph.D. under Milton Friedman at the University of Chicago, and I'm a firm believer in the principle of operation of markets.
The market is working, and if you take a look at the Canadian banking system, it's the envy of banking systems all over the world. We're being examined by the Americans, by the Europeans--as in maybe we should go towards the Canadian banking system. We have a few banks with a large number of branches, as opposed to the United States, which had a huge number of banks with no branches. Their system didn't work.
During the Great Depression, 5,000 U.S. banks failed; not one Canadian bank failed. We have a system that's working. Our payment system is working, our banking system is working, and it's regulated. We shouldn't put more regulation in it on such things as interchange fees, which make it not work, which make it inefficient. We have a system that is working. If it ain't broke, don't fix it.
