What's the big revelation?
VAT is still regressive, because just like "rebates" that have to be filled out and sent in later, many who pay VAT will never see the rebate.
I think the frame of "raise taxes" should be replaced with "raise *tax revenues*, hopefully by removing decades of accretion of deductions" ...
Most people are "against" new, higher taxes; most people could get behind the removal of things that they see as having been abused.
