There is indeed something very wrong with that. You pay your taxes which help fund research and then you are charged exorbitant prices for access to the resulting articles. At the time I quit maths there were a smaller uprising among some mathematicians trying to break away from the large old, but unfortunately also still prestigious, journals. "Algebraic and Geometric Topology", an online journal, was formed when the entire group of editors on Elsevier's "Topology and its Applications" resigned as a reaction to Elsevier's increasingly whack pricing policies. Later the same happened for the top journal "Topology", the resignation letter is stil linked at John Baez's site: http://math.ucr.edu/home/baez/topology-letter.pdf.

Likewise books, lecture notes etc. written by lecturers should be made freely available. You want to make money on a book you likely created most of while supposedly doing your paid job? GFY.
