Your argument is the one that's actually dumb, it seems like you don't know how taxes work. Historically the tax bracket has always increased as you earn more money. Like your example if you only make 50K taking 20% only leaves you with 40K that's gonna hurt alot more than being left with 800K.The issue is that with some weathly like Romney they use loopholes to pay significantly less. No one likes paying taxes so ofcourse no matter what you make your not going to be particually "happy" losing part of your income.
taxes "work" depending on who is imposing them. Thus the disagreement between parties. In my opinion it makes no sense, and is not fair to increase, because due to their high salary whatever (reasonable) percentage they pay will actually be a lot more $$$ anyway than the average person. Besides, those criticizing Romney are acting like raising taxes on the "rich" is going to save the economy. LOL, those people are the ones that have no clue about the economy, which btw relies on the middle class and their taxes, which if reduced too much causes a gov deficit ( obv added to the careless spending etc.)
you disregarded the principle of discretionary income. if person A has 20k and person B has 200k, it would be unfair to make them pay the same rate. if they both hypothetically pay 25% in taxes, person A is left with 15k and person B is left with 150k. say basic living necessities cost 5k, person A now has 10k and person B has 145k. this remainder is discretionary income which can be used for miscellaneous purposes. notice person A has lost 50% of his income while person B lost roughly 27% of his income. if you increase the taxes on the upper bracket by a few percentiles (say increase tax rate to 27% and leaving him with 141k extra), this allows you to lower the rates for the bracket of lower income levels, which allows more general spending into the economy by the middle and lower classes, which make up a much larger percentage of the economy. if you've ever taken an economics class you'd know that almost no sound-minded economist approves of a flat tax rate
