It doesn't matter what the rate is. The point is that if it is a sales tax people will be constantly reminded of what their real tax rate is. From this they can make education decisions when they vote.
Whatever it might start out at, my guess is that it will steady out at around 15%.
Even if the tax take is EXACTLY the same, the American people will be more aware of the tax burden if their money comes into their personal hands first, and then is paid out later as a tax. Most American people, sadly, think in terms of their take-home pay, which takes the focus away from the tax burden they are paying.
