I especially agree with revamping the tax code. I'd like to see it simplified to the point that we can shrink the enormous size of the IRS. Give Romney some time with public speaking, it took Obama 4 years to figure out how to do it without a teleprompter, though GW never seemed to get the hang of it.
Personally, I don't think that just revamping the tax code will do it. The entire system needs to be rethought because it's just not fair, and there's no way to make it fair without throwing it away and starting over again from scratch.
I could personally live with a consumption tax. That's really the only fair way to tax people. Taxed on what you spend instead of what you earn. Rich people will naturally pay more, but everyone will contribute something. If you buy a $2k used car, you pay a flat rate on that $2k, but if you buy the $2M Bentley, you pay the same percentage, but naturally the amount will be much more. It's the only fair way to tax people. Then you wouldn't need an IRS at all. It would also encourage investment, since you're no longer taxed on your investment income at all. It would also encourage people to save and not incur more credit debt.
It would also get rid of any loopholes.
