I would depend on how the referendum was worded and how much real education was done with the populace.  In my opinion, the real problem with tax reform is people not processing the scale of the numbers and the purchasing power behind those numbers.  For an example, Trump's fraudulent business school just cost him 25 million in his class action suit.  That sounds like a lot of money and it will mean a great deal to the people in the suit, but if Trump really is worth 5 billion, 25 million of a 5 thousand million net worth still leaves him with 4,975 millions.  So his settlement figure is not exactly going to seriously impact his net worth, much less leave him at a poverty level.  I just wonder how many people can really conceptualize the disparity between the really rich and the average Joe.
