Inflation-adjusted Textbook Pain Multiplier for Decision-Makers
or [for OER experts]
One of the Famous Graphs in the OER World is Backwards

I've used [versions of] the following graph many times when talking about the cost of textbooks, as part of building a case for OER. But I actually think this graph is basically backwards [and upside-down, inside-out, and otherwise non-optimal].
 
There is no denying that it does have a certain visceral impact....

...But I think that graph could be improved, actually to show some measure of the gap between the price of textbooks and what our — inflation-adjusted — intuition says they should cost. The measure should be based on comparing what textbooks cost when a particular person is looking backwards from today to the cost they remember from when they were a student.
