I understand what you are saying but we have to think this through to the end result. The government waives all income tax. Suddenly there is no revenue, no medicare, no medicaid, no government benefits of any kind, no armed services and the list goes on.
As citizens of this country - we have to do our share. Now is that share fair? Not necessarily. I do think the tax code needs revamping so there is more fairness across the board such as a flat or consumption tax.
