Knowledge has been a money game since Ancient Greece, (before then, in the cradles of human civilization, it was for priests only, so the historical roots outside the Proto-Euro front are no better.) You, surely, want to be compensated for your work, correct? Same for academics, journal publishers, librarians, and the gravy train tricks way down, to lab and library janitors.
However, the world is changing. The cost benefits of online publishing are being passed on to academic institutions, so there are deals to be found, just have to have connections.
