Regressive tax? Maybe you need to look that one up, anon. I believe REgressive taxation is the opposite of PROgressive taxation. Meaning that the poor would pay a higher percentage of their wages in taxes, as apposed to the current system where the rich pay a higher percentage of their income in taxes.
The fair tax simply has to do with how much you spend - if you are rich and spend a lot you pay a lot in taxes. If you are poor and spend a lot, you pay a lot in taxes. Of course, the reverse is true. It encourages saving and responsibility.
And what in the world? The author said that an opponent argument is that those in the lower socioeconomic class would have trouble understanding the new tax and would be unfairly taxed?
The fair tax could easily take less than a page to write. How many thousands of pages is the current tax code? Even Timothy Geithner (the current United States Secretary of the Treasury, former president of the Federal Reserve Bank, and founder of Turbo Tax) can't figure out our current tax code. The fair tax would be unbelievably simple in comparison.
The fair tax is, in fact, fair. Those below poverty would still get welfare programs and perhaps even "prebates." Those who make an illegal living would now pay taxes (all those crack dealers who currently avoid taxes).
The vast majority of us would now have "skin in the game" and would see our taxes taken from us on a daily basis. This would encourage us to be sure our politicians spend our money wisely.
