I already showed you (twice) that currently the top quintile already pays 29.6%, a flat tax would not increase their burden:
According to administration data, the median effective tax rate for the middle 20 percent of U.S. taxpayers is 13.3 percent, including income, payroll and corporate taxes. For the top 1 percent of taxpayers, the rate is 29.6 percent, according to the 2012 Economic Report of the President.http://www.debatepolitics.com/break...s-advance-buffett-rule-23.html#post1060406047
You keep forgetting what I already showed you, you don't read the links and you keep asking the same questions over and over again. Further, you keep denying that a flat tax doesn't increase the burden for all, you keep switching back and forth between "everyone needs to pay more" and "the lower earners need to pay more". If you want everyone to pay more, a flat tax won't do it. If you want to increase wealth inequality, a flat tax will do that.....because (for the upteenth time) it would double the rate for mid and triple it for the bottom quintiles.
You are arguing for the tripling of the burden for low quintile earners, the total swallowing of their disposable income while their state tax burden remains the same. You are pushing them into poverty while not changing the tax burden for the top. Again, you increase wealth inequality.
Again, you said you wanted to pay more, so go ahead and do it...no one is stopping you. If you can afford it...do it.
