Jones, I think everyone would agree that investing in Schools, Medicine, Space Programs and Road/Infrastructure would be a tax worth investing in. That would certainly be the correct thing to do.
But being extorted to pay for terrorist activities, wall street bailouts and that circus that is sometimes called the senate is problematic when considering a functional return on any tax-investment.
The question is asked to "avoid" not to "evade" the extortion racket called taxes. The monies taken are pooled and spent on non-viable and extremely wasteful expenses in areas that do not provide good solutions for the country as a whole and that is worrisome.
The distinction between the tax authority and the mob are becoming indistinguishable as of late and seeking methods to channel monies through more appropriate channels without being diverted through wasteful channels is just being economically sound and smart with ones income.
