It's another interesting example of how to deal with debt.
The problem here is that this system has become incredibly Byzantine. It takes an incredible amount of time just to follow all of the transactions, etc. The issue is that at the tail end or the front end of the system there is a load of rewards points, bells, whistles, etc., which have effectively distorted the system.
Professor Lee rightly analyzed the Australian system. There, they tried to do something. When you only try to do one thing in isolation, naturally the credit card companies react and either load up fees or do something else. That's the lesson to be learned in Australia: either you do it all or you do nothing.
Professor Lee, you seem to be driving to a “do nothing” argument; other than, well, we need more education and we need to be more literate and all that sort of good stuff, it's really “don't do anything”. But don't we really want a credit card system that looks a little bit more like the interchange debit card system, which basically runs on a cost or a cost-plus system and doesn't have a whole whack of bells, whistles, rewards, incentives, etc.? Then you'll actually get the best of both worlds. I'd be interested in your comment on that.
