The central thesis of the article is this:
> Don’t blame books for being too expensive. Everything else is more expensive, and that’s why you can’t afford books.
College textbook pricing is a function of the aforementioned rate of increase of everything else becoming more expensive, not a function of the cost of books increasing generally. They are, the author argues, decreasing, unless you introduce external distorting factors.
poppycock. the author is wrong about textbooks.
The article is correct that recreational books are below for cumulative CPI. College textbooks on the other hand are at ~ 3 times the rate of general inflation.
