The problem with liberals is, you can't think dynamically, everything is static. You assume consumer prices will remain exactly the same, and that we'll simply realize this 9% increase across the board on all prices of all consumer products, without exception... and that wouldn't be good. But here's what you are failing to understand, the corporations would be paying 9% corporate tax instead of the average 23% they are paying now, therefore, they COULD conceivably, reduce their retail prices by as much as 14% and realize the exact same profits, meaning, you would actually pay 3% less than you are paying now, for their product... you'd still be paying the 9% sales tax, but the price has been reduced, so you would actually pay less. This wouldn't happen on everything, it would depend on supply and demand, competition, etc... but on average, we wouldn't see a static 9% increase in prices across the board.
