The reality of the analysis you drew was an excellent one and I am sure many students even though they may complain, perhaps do not realize the truth presented in your argument. For all of time people have wanted to make money and to prosper and therefore are forced to create new mediums for making money, or more often than not transforming old mediums slightly and passing them off as new. This is more or less what I take from what you are saying is that they manage to just go back through a text and somehow re-analyze it slightly and end up being praised. Meanwhile, the new addition of the book is used and the price skyrockets, thus rendering the old text obsolete and worth nothing as the market for such is concerned. A few after effects of this are students having to pay exorbitant amounts of money for books each semester, even when they may be able to sell a few back. Why do universities indulge in things of this nature? These questions could definitely use some answers...

This could easily become source for a paper, the only issues you may come across is the fact that it obviously would require a decent amount of research; so I think,  though I have been wrong in the past.
