Check out this comparison of two proposals of flat and fair tax against the current income tax structure. I am personally would love for the fair tax, basically national sales tax with exemption for food and medicine and other basic necessities, to be adopted. It would encourage savings and investments since you would only be taxed if you spend. It would abolish the IRS. It would keep the people constantly reminded of the tax being taken away from them to finance the bloated government beaucracy everytime they buy anything.

I could not agree more with this article urging reform at NASA.
