Yeah, that is fair. I guess my gripe is with the idea that research universities charge undergraduates more at all. If anything, most students get a much worse experience and learning environment as a result.
My own experience was that professors who were not currently research oriented tended to have a much more personal interest in actually teaching- not just the material, but in the practice of pedagogy overall.
Compare that to researching professors (or worse, their grad student substitutes) and it is often a night and day difference. All you're really paying more for is often the name on your diploma at the end of the day.
