This becomes even more obvious when one considers ALL forms of taxation and not just "federal income tax." Those that point at federal income tax to describe the entire tax burdens of our citizenry are either stupid or lying--probably both.
Which is why government should be at the lowest possible level to achieve the sort of society we wish to have. The more layers of government involved in any given situation, the more taxes will need to be collected, absorbed to fund the levels of government, and the less money will be available for those intended to benefit.
Probably true--except for that nagging problem of military protection from other gigantic governments. The "cold war" enabled the U.S. government to become a military state and enlarge its police powers over its population. It is perpetuated today by the never-ending "war on terrorism."
Even the military establishment is bloated through several layers of government and is as corrupt as any other government industry with those in government enriching themselves with payola, graft, bribes, etc., most of which would end if we got the federal government out of the benevolence business and removed the ability of those in government to enrich themselves by misusing our money.
At least the common defense is a constitutionally designated responsibility of the federal government. Farm subsidies, social engineering, and paying people to remain poor is not.
