2. sales tax = state taxes. i would love to see the national government move to a Fairtax-esque system, mind you, but what we are talking about here is federal policy
3. those who are least likely to be net tax payers (myself a year and more back, for example, i think this is the first year i will be a net taxpayer) are also those most likely to rent, and thus will be the demogaphic least likely to pay property taxes
4. property taxes = local taxes and state taxes. see point #2
5. the one you miss, but i'm not sure if it should be included, is the payroll tax, which is regressive and which all legal employees pay. now, nominally those are "contributions" to a particular program, but i think we all know that they are counted as part of the general revenue, and we might as well consider them as such.
i would love to see simplification of the tax code to limit deductions to child, education, and health. as i recall; in my plan those who wished to vote had to give up all tax breaks and deductions.Also, the premise ignores tax breaks, especially to businesses, and corporate welfare provided to government contracts, especially no-bid contracts.
