<p>What kind of circular logic is that? Older versions remain attractive BECAUSE the new ones are simply too expensive. New versions are expensive because it is nothing short of a racket where authors and publishers are in deep cahoots. Professors routinely push new versions because of their OWN interest. </p>
<p>The vast majority of the textbooks do NOT need continuous revisions … it is nothing short of blatant thievery … and the fact that the same books are sold overseas for a lot less (to respond to market forces) illustrate that the book publishers are simply milking the cow for all it has. </p>
<p>Interestingly enough, it is more noticed in colleges because for most students and families, it is the first time they see the racket in action and the first time THEY pay the bills. The practice, however, starts in the early years of K-12, with the same bandits sharing the spoils.</p>
