Just part of the definition from MW:
marked by impartiality and honesty : free from self-interest, prejudice, or favoritism
Free from favoritism.......hmmmmm.......our current tax code shows plenty of favoritism, IN BOTH DIRECTIONS between the bottom that pays none and the top that has plenty of loopholes. So I have a hard time seeing a problem with everyone paying the same percent, top to bottom. The top looses the loopholes, and the bottom actually has to pay something.
Fair share to me is EVERYONE paying the same across the board, 9% is hardly most of my income. What exactly do you see as fair, since everyone paying the same percent of tax doesn't seem to cut it.
Also, I'm not seeing any numbers from you on the first part of my post......
