Well said!The problem with those proportions is that you really need to look at taxes as a percentage of a living wage. What portion of subsistence income does any given tax bracket pay?
If you work at Micky D's the small dollar amount you pay in taxes has a much higher impact on your overall ability to make ends meet at the end of the month. Therefore, it reduces your ability to ever get ahead in life.
If you make $1M+ a year the 50% of that the government sucks away has no impact on your subsistence income. And currently, with the low long term capital gains tax, the rate that most wealthy Americans is taxed only amounts to 15%.
