I feel that it is the fairest possible tax, as it recognizes the basic fact that society helps contribute to one's income through the services that are provided, therefore those who earn the money have an obligation to give a portion of it back to help the less fortunate.

A sales tax is much more unfair as it is highly regressive, hurting poor people more because poor people spend a much larger percentage of their income than do the rich, thus the poor would actually pay a much higher rate. The sales tax also hurts the economy by artficially raising prices.
If the government truly has no constitutional authority to do the things that it is doing, then get them declared as such by the Supreme Court. Otherwise, if the Court refuses to agree, this argument fails to hold much water.

In fact, even if there was, society is not the federal government. You are paying nothing to "society" you are paying to bureaucrats who are going to waste your money like it was corn.
I don't think a sales tax is much good either. But look, New Hamphire has made it without any sales or income tax. But let's assume a major tax is needed. A flat income tax of like 15% would be sactisfactory. Oh, I see, the sales tax hurts economy. And I suppose the income tax doesnt...
You know damn well the supreme court would never declare that inconstitutional, first ecause it is dominated by liberals, and second because the Justices have to pay back for who appointed them by letting some inconstitutionalities pass by.
Now, I wish you would tell me, where is the federal government granted power to creat a public school system, to creat social security, to establish Welfare State, and to "create" any federal crimes other than treason, high sea piracy and counterfeiting?
