No reason for income taxes at all. Especially not federally. State taxes are a potentially different story as we are (in theory, though not in practice) in more direct control of our local government as reps from California can't come in and throw their vote to raise taxation like they can with the federal government.

Further to the point is that it's like these governments are playing a game of "choose one", with a myriad of different taxation options in front of them, and they just flip the table over and call everyone choice-phobic and cries victim until each other player offers up one concession each until the "choose one" has become "everything".
