Yeah the textbook cartel is outrageous. I started a textbook publishing company to fight this!

I was working on web copy describing how crazy the mainstream textbook prices are, and used the price C$300 for the calculus book, trying to be flippant (to exaggerate the competitor price to make my prices look better). I decided to check the price in the bookstore, and to my surprise the price was even higher than that! (sold as bundle: book + exercise manual + solutions manual). When your real prices are higher than the pricing people use as hyperbole, you know there is a problem.

It makes no sense—for a subject that has been around for 300+ years, and virtually unchanged for the past 100.

This is the kind of thing that is counted as "economic growth", too.
