The assumption that the rich will change their spending habits is not that illogical. They already find loopholes in the current system to save money. What makes you think they wouldn't do the same in any other tax system? That is to say, they may still spend like the rich, but would do so in a way that would circumvent taxing. In the current system, at least the rich people have to pay accountants and lawyers to find the tricks and there's money that trickle down. In a fairtax system that might not be the case.
