Yeah you are right and because of that "wealthier" people got a bigger percentage.
You need to take the cost of living into consideration a citizen have to pay compared to what the average get on money in the US.What about pension;healthcare;education et cetera.
Those things can cost in the US. They shouldn't!
if you have everything you need,you have no "fears"...You don't care about "too high taxes".Trust me.-Of course only if you work or go to school.If you are productive for your country!
Live is only good if luxuria ;)
