First, try getting the almost 50% of the people in this nation who DON'T PAY ANY INCOME TAX to go along with it.
And the constitutional amendment that is necessary to abolish the income tax, would be next to impossible to pass.
IMHO the chances of a NRST is 0%!!!
First of all there is no such thing as your "50% of this room who don't pay any income tax". Even if you do not file tax returns and do not have an employer who witholds payroll taxes from your wages you STILL pay taxes. You just don't know it.
Taxes increase the prices of everything you buy by from something like 20 to 40%. That's precisely what the pols hope for - that the citizens are so ignorant that they do not realize they are greatly taxed sub-rosa. Attitudes like that make you dead meat for the politicians and their control of your lifestyle by tax laws.
You might read the comments of Beardsley Ruml who implemented the withholding taxes for FDR - and this was in 1946:

You should also realize that repealing the 16th (which IS called for by the FairTax bill) is not "impossible" to pass at all. Once the FairTax becomes law and the IRS is abolished (2 things which the bill does once it is law) there is no function served by having a mechanism to re-institute an income and - in fact - the citizens by and large would not allow it once they have tasted the tax freedon offered by the FairTax. The 16th, then, will be an anachronism and fairly easily repealed. Remember Prohibition ant the repeal of its amendment.
Pols have as Job #1 their own re-election and with a stirred up populace they are not so courageous at to buck a widespread trend of that sort. That's how Prohibition was repealed ... grassroots support for its repeal.
You merely assume you are defeated before you start. You're not. Read up on the FairTax bill, contact your congresmen and let them know you want "fini" written to ANY FORM of income tax.
