Spending and ways and means of collecting taxes are two separate things, and the latter matters.
The current income tax system is largely hidden, and/or collected at the wellhead.
A national retail sales tax, conversely, would be visible, and collected only at the point of sale.
And the divide and conquer mechanisms of the current system would be gone. The protection racket would be dead. All Americans, finally, would be united in one self-interest: lowering the rate.
Which could only be accomplished by reducing spending.
Yup, and then generate a monthly check for at least half of Americans to offset the huge sale tax is the answer? Do people like you realize what a huge bureaucratic organization, bigger than the IRS, will be needed to enforce, analyze rebate, etc etc etc. This is just as much crap as the current system. Now come back and give me the paycheck will be bigger! Not for freeloaders and half of America is in that class now.
