A. How much money do Elsevier take from universities each year?
B. How many years will it take for Elsevier to go bankrupt without income from said universities?
C. How much money will it take to buy *all papers* from the auction at the bankruptcy of Elsevier?
If A * B >= C then all universities could save the money they spend on Elsevier to put all of their papers in public domain (Assuming B is not impractically long and assuming Elsevier don't do something evil and down size enough to sustain themselves indefinitely while sitting on a hoard of papers).Once the content is freed universities can invest their publishing money in something more worth while like open access distribution networks.
