Let's be fair. Under the current system, I could earn $20K per year, pay zero income tax and even have an earn-income credit that gives me more money than they withheld for social security. So I don't have to be a homeless bum under the current system to be paying zero taxes either. Both systems are equally repulsive in that they must collect over $2 Trillion to pay for mostly socialism and government waste.
Nothing fair about that since you pay no tax at all, Rightie.
With the FairTax even though you may get a prebate, every taxable purchase you make contributes sales tax to the revenue box even though you get some back as the prebate.
With the income tax you have others bearing your tax burden since you pay no tax at all.
