Another point about consumer sovereignty: producers are consumers too. Suppose you want to hire me to teach a philosophy course with only multiple-choice tests, but I refuse to offer the course unless I can give essay tests. Does this conflict with consumer sovereignty? Not at all. Teaching the course my way is a consumption good for me; it's part of the price I demand for my services. And of course each of us is free to take or leave the other's offer.

If you're a service provider, sometimes you compete with your customers for your own services. The customer is always right -- because the party to whose wishes you ultimately decide to cater, the party you treat as being"right," is thereby your customer.
