You are taking me completely wrong.
I am not saying that current taxing system is any better than fairtax.
I am saying that fairTax is a fraud.

First of all, any type of compulsory taxation is wrong and unreasonable by default.
Taxation can be said right only if it is Voluntary.

Under the Fair Tax, the poorest Americans are exempted from taxation and the the tax burden is based on how much you spend.

And why should you or I or anybody worry for the poor or rich or anybody else?

Simple thing is, consumption is not always fixed nor is it dependent on whether you are poor or rich.
No matters if you are poor or rich, if you are suffering from diabetes, you will need insulin.

The Fraud of FairTax, instead of being a step towards, no tax or Voluntary taxation, is just another fraud of same redistribution of income, snatching from the earners to pay for the lazies. It is just RobinHood like Robbery.

Then Fairtax System has got its own problems.

Problem #1:The FairTax hides the amount of sales tax being paid. Boortz explains how "the FairTax was designed as what's called an 'inclusive' tax—that is, the tax is included in the list price of the product." He reasons that "since our current income taxes are figured on an inclusive basis—that is, they are taken out of our paychecks, not added to them—it was decided to handle the sales tax in exactly the same manner." How could someone write a whole chapter on the evils of the withholding tax and then turn around and recommend a hidden tax like the FairTax? Boortz even has the audacity to claim that with the FairTax the "consumer is completely aware of what he is paying." Really? Suppose the FairTax is implemented next year. Go stand in front of a store and ask the typical American how much federal sales tax he paid on the item he just bought for $139? Give him a calculator and ask him again. Unless he is familiar with figuring percentages, the average American will not be able to tell you how much sales tax he just paid.

Problem #2:The FairTax is progressive. Boortz correctly identifies a progressive income tax with Karl Marx. Yet, because of the prebate, the FairTax sets up a progressive tax system like we have now. Millions of Americans will pay no taxes at all. Others will have some of their taxes offset by the prebate. "The rich" will still be paying the majority of the taxes—something Boortz says he considers "class warfare."

Anyways, you have already commented that you have no problem regarding that.
But I do have a problem with that, and many more will have the same problem. Why should I pay for being rich? Why should I pay just because someone else is poor?
It is ridiculous and it is just a form of Sacrifice, and sacrifice without consent is a crime in my eyes.

Problem #3: The FairTax is an income redistribution scheme. Boortz calls the Earned Income Tax Credit "a prime conduit for income redistribution from high-income earners to the poor and middle class." Why, then, would he promote a FairTax Plan with a prebate that in essence allows the majority of citizens to not only pay no taxes, but in many cases gives them money over and above that which they paid in sales tax? What's fair about making "the rich" subsidize the poor and the middle class? Boortz calls Social Security an "income redistribution and welfare program." But under the FairTax Plan, Social Security is even worse. At least now it is funded by payroll tax contributions that are independent of deductions for federal income tax. Thanks to the prebate, many people will receive a free retirement program via Social Security who never contributed a dime towards their retirement, or as Boortz says: "All benefit and no burden."

Problem #4:The FairTax creates new tax collectors. From doctors and lawyers to garbage collectors and tree trimmers—multitudes of individuals and businesses that never collected taxes before will be turned into tax collectors for the federal government. Will a teenage babysitter be required to collect the FairTax from her neighbors?

Problem #5:The FairTax creates new taxes. All Internet purchases will be subject to the national sales tax. So will heart surgeries, kidney transplants, and appendectomies—plus the drugs prescribed by the doctors doing the procedures. Want to attend a baseball, football, or basketball game? Better save up a little extra to take care of the FairTax that will be imposed on your tickets.

Problem #6: The FairTax creates new taxpayers. If there are no exceptions and no exemptions then churches and other non-profits will be forced to pay a national sales tax on every purchase. The FairTax will basically do away with not-for-profit entities. The FairTax would also count as taxable the purchases made by federal, state, and local governments. This means the government will be using taxpayer money to pay taxes to itself.

Problem #7: The FairTax makes it easier for the federal government to raise taxes. All Congress has to do is slightly increase the initial 23 percent rate. A penny here, a penny there; a quarter of a cent now, a half of a cent later. Just a little at a time, of course. It might be to compensate for inflation, to give seniors a cost of living raise, or to pay for some manufactured crisis like bird flu . Since the federal budget goes up every year, and the FairTax is supposed to be "revenue neutral," the FairTax rate will have to go up right along with the federal budget. You can count on an increase every year, for if government budgets are not under control now, why should we expect Congress to magically become fiscally responsible just because the FairTax is adopted?
Furthermore, since Social Security and Medicare would be funded out of general revenues the FairTax rate would also have to go up to fund the ever-increasing cost of these programs. Then there are the escalating costs of the new prescription drug plan. And if the amount of the prebate "is updated every year to keep up with inflation," the FairTax rate will have to be raised in like manner. How can Boortz recognize that "there is absolutely no limit to the government's desire for your money" and then express hope that the FairTax rate "will go down in the future" if "Congress can keep government spending down"?
