I don't think the "FairTax" plan is a best option to reform the tax system.
Firstly, no country has ever completely abolished the income tax and implemented solely a consumer tax system. There is no evidence that this plan has or will work as you presume.
Secondly, the FairTax plan would involve issuing monthly prebates to lower income families to assist in paying for expenses. Who is paying for these prebates? Where is that money coming from? It would come from the tax collected from everybody that pays for a good/service, yet the prebates paid for by everybody will only be issued to some. That sounds pretty close to "spreading the wealth."
Proponents of the FairTax plan claim that it will eliminate the IRS and save tax payer dollars from funding that government agency. I agree. However, the IRS will be replaced by a Prebate agency, effectively transferring money allocated for the IRS to this new agency and not saving the taxpayer any money.
Conversely, the Flat Tax system has already been adopted by over 40 countries and has yeilded great results. These countries have experienced increased revenues, increased nominal GDP, and their economies have been stimulated. The Flat Tax also rids the system of loopholes, eliminates excessive deductions, exemptions, and double taxation, and ensures all income, including capital gains, is taxed.
I appreciate your enthusiasm and recognition of our flawed tax system, but there are better solutions then the one you have proposed.
