Too many people still seem to believe that it's impossible to tax top wealth - that no matter what any taxes will just be passed down.  In fact that's not how things work at all.  Prices at consumer level are not determined entirely by cost, but rather by demand.  Any large corporation that raises prices as a result of this measure will simply be outbid by its competition.  If this measure passes we will send a clear message to the nation that we're done believing the trickle-down fantasies that we've been working under since the early 1980s.
