Sales taxes are naturally regressive, as they target people who need to purchase things to survive. They also have a chiling effect on the economy by directly raising prices. In order to shift the tax burden onto those who can afford it:
1. Increase income tax rates, but exempt the first $x of income from all income taxes, including fica/ss tax. x= enough money to survive and buy transportation to work and childcare in any major city. Exempting more money will give the economy a boost, as more people can afford to pay for services and buy products. By contrast, decreasing taxes for the richest 1% does nothing for the economy, since they already have plenty of money to spend on goods and services.
2. Eliminate all taxes on food not prepared for immediate consumption. Where I live they have taxes on food, that is regressive and oppressive.
3. Exempt mostly renewable fuels from the existing 18cent/gallon fuel tax, and increase taxes on nonrenewable fuels. This will target wasteful rich person activities such as motorboats etc. that nobody needs to survive. Most high fuel consumption activities and devices are luxuries, not necessities.
