I think the coalition of private school voters is incredibly small relative to public school ones. There is a much larger block of voters to oppose measures that cost the system money than there is to support measures that save private school users money. I think you do have to convince public school users they will save money to have the votes. Public school users only save money by the behaviour change I posited.
