I'm sick of all this talk about supply and demand. There are other factors in economics, you know. (Which is not to say that he doesn't have the right to charge what he wants, nor that $75 is outrageous.)

For example, let's assume that the Beatles were to reunite (and that John and George were still alive). They would go on tour and the demand would be phenomenal. But if they charged $3000 for a ticket, how many people would buy them?
