Is it possible that the decline also has to do with the decline in quality of humanities teaching? My undergrad writing "teacher" was a terrible grad student, intent on pushing a social agenda on the class. I certainly wasn't going to take any more than I had to. My "intensive writing" teacher has a very extreme political agenda attached to a geography class. I sucked it up, but vowed never to venture into his department either. I don't think it's pure practicality that's holding English back. Many CEOs are English and History majors. It's the quality of the teaching.
