Be aware, that one of the aspects of the FairTax that advocates tout is it's progressivity (the effective rate rises with spending due to the effect of the "prebate".)
Ultimately, any method of taxation who's collection is implemented as a part of normal commerce (income or consumption) is doomed to become normal and accepted ... it disappears into the noise of every day life.
If you want to truly impact an individual's sense of the impact of the size of government, then make the collection of taxes a periodic "lump sum" event OUTSIDE the monotony of normal commerce. Have the Taxpayer "write the check."
