So I guess we are in agreement that prices are going up substantially if the FairTax were to pass?

No, you made that up. That prices may change is immaterial until you take the corresponding change in wages into account. Real prices will remain stable (for the first year or two). Purchasing power will remain stable. Ask someone you trust.

Unless you are on a fixed income, and fixed after-tax savings and don't have wages.
