Not to mention that there is a huge misunderstanding of how progressive tax rates work. A very affluent businessman was on tv saying they would essentially have no motivation to work if the marginal tax rate increased for him when Obama was campaigning. His idea was that the tax bracket above 250k per year would somehow affect his entire income if he earned more than that figure so he would only want to work until he had 249,999 dollars and then stop making money to avoid "making less money". Of course the marginal tax rate is the rate that your money is taxed above that threshold. In this case the tax rate would go from say 15% to 20% on the money earned after 250k. Let's say you made 260k that year. Your extra tax burden because of the marginal rate increasing would be 20-15= 5% on the 10k dollars. You don't get taxed an extra 5% on all your money made like that fellow thought.
Flat tax is regressive and sales tax is regressive.
