I'd like to see these guys explain price discrimination with their theory of pricing. "Third Degree Price Discrimination" is a great example of how the market dynamic determines price. The same product is sold in different markets for different prices. What's the difference in the markets? Not costs, it's the elasticity of demand.

No reason to do so at all. We're not discussing pricing practices and tactics for alternate marketplaces.

That's merely one of the red herrings you love to drag out. It is meaningless to the FairTax discussion.

It is virtually impossible to understand these matters without a firm grounding in micro theory. And micro is the most difficult part of economics.
