Until there is data, not talking points or vague references to other models, it is in face just a rant. What is the actual supply? What is the actual demand? What is the curve function for the supply and demand lines for education and workers? What factors of those functions are accounting for teacher unions and what is the source data that you used to fit those functions in your model. I don't mean a handful of words - I mean actual data with numbers, or at least a citation to a work that has that available. Waiting for Superman may include those - I haven't read it.

As for the attempt to derail over "politeness concerns" because I used the word rant - I won't bite.
