I agree in principle.  I'd probably make a few very minor tweaks, but I am 100% for eliminating all taxes except a sales tax and making every receipt show how much we are paying to each taxing authority.  People need a reminder of how much they are actually paying.  When they are nickel and dimed to death by a 100 different taxes, they have no idea how much they are actually paying.  Many taxes cost more to comply with or to enforce than the revenue they bring in to the government.  It is such a waste.
