Yes. I have dealt with this question in my classes, as you can imagine. I don't think you should be regulating that. If we want to drive down prices, we know the answer. We've known it for 300 years. You introduce more competition. More firms drive down prices. A smaller number of firms allows prices and margins to be pushed up.
Secondly, in terms of the code of conduct, I'm not advocating that anybody act unethically. I've been dealing with business for 40 years. I don't know anybody in the corporate world who comes to work and says, “I'm here to exploit and hurt some employees.”
