Problem with this is not everyone work (ie. labor) for a living.
The vast majority of us work for a company and thus get a paycheck for our labor (be it physical labor, a desk job, etc.) so we get x% of taxes taken out for that labor.
However there are others (mainly the rich) that don't do this type of labor work. They use their funds to invest and make more money (capital gains), or just leave it in savings and live off the interest. So should that be taxed at the same rate?
I don't know but I suspect if you tax say everyone at 10% of whatever/however they make their money the .gov will end up losing money I think.
^ WINNER!!! WINNER!!! Chicken Dinner!!!
1) IMO, capital gains should be tax free. You have already been taxed on the money once when you originally earned it - now that the money is working for you, why should you be taxed again?
2) I think the flat tax level it somewhere around 17%. The democrats don't want a flat tax because even the lower income (democrat voting) people would lose money. Then maybe their eyes would be opened to smaller government-smaller tax bill.
