Why not start with the publishing companies…every semester they sell a “New Version” of the book and charge waaaaay more money than the book’s worth. Putting a cap on the amount of money publishers are allowed to charge schools/regulating the “New Version” distribution of the publishing companies – i.e. we don’t allow them to come out with an identical version of the same book every year, calling it new and charging ridiculous amounts of money – would definitely make an impact. (Books would cost $50 as opposed to $200).
