A new analogy for teaching and why we should get paid like a million dollars a class.
1. Each class is like it's own small company. You need to make promotional materials for it (syllabi, handouts, etc.), you need to do research about the product (read books), you need to incorporate that research into the product (lectures, discussinos) and you need to persuade your customers (sadly, your students) to buy it (tests, graded work). The ideas in the discussion and the lecture are unique therefore should be patentable (although there may be some legal business about patenting speech but if we get Disney in on this, I'm sure we can work around it). Oh, and you make copies yourself which makes you an administrative assistant to your own boss which is also you! You're a very, very busy person. You shouldn't take any unsolicited phone calls. Have them send the prospectus to your office and you'll take a look at it later.
