May be America needs a much bigger change than what you are looking for.

When you say people don't mind giving taxes, you generalize the people. You ignore those who Do mind their hard earned money being wasted the way it is done.

May be it is the time to end the RULE OF MAJORITY OVER MINORITY. Period
May be it is the point of time when the sovereignty of an Individual need to be safeguarded against the brutal rule of majority, it is the time when the liberty of the smallest minority, that is the Individual must be recognized and respected.

If people don't mind giving their hard earned money as taxes to be wasted by these socialist goons, why to force taxes then?
Let it be voluntary taxes, if people do like to give such useless taxes, if people like such useless bureaucratic systems totally denying freedom for the Individual citizen of a state, then let them decide to give monetary contribution according to their voluntary free-will. If people sincerely don't mind giving taxes, then they will keep giving on the charity to the server of the citizens (that is the government),
The system of compulsory taxation simple refutes your idea of people's choice of minding or not minding the taxes to be given.
