Fewer still would take us seriously. Perhaps someday society will be receptive to the idea of virtually eliminating federal taxation, but that day is not today. The answer, of course, is that it shouldn't. The point of a tax code is to raise revenue, not to punish success. The code contains literally hundreds of exclusions, deductions, and credits that subsidize specific industries.
Liberals see something here that conservatives are often too slow to pick up on.
That is, if the point of a tax code is to raise revenue, then it should not be a tool to subsidize private industry. Then there are two problems that people with any political ideology can be upset with. The first is the double-taxation of savings. The current code taxes the interest we earn on our already taxed salary, thus creating a disincentive to save. Many otherwise frugal people would rather spend their money now, because after Uncle Sam gets his share, there isn't much left for that rainy day they were saving for.
