And, in most circles, preparing students for successful careers is considered a legitimate goal of higher education. Isn't it?
Actually, not necessarily. At some colleges, especially Community Colleges, preparing for a career is indeed the entire point. Many state schools tend to value job placement after graduation, too, and research universities may or may not take it very seriously as well - depends a lot on the particular college and particular discipline. However, at a lot of liberal arts colleges, a statement like that at a faculty meeting will get you tarred and feathered; the professed point of a liberal arts college is to "expand students' minds" (if I may paraphrase) and the nitty-gritty of "preparing for a career" is considered anathema to that.
And let's not forget: preparing students for a career assumes there are careers to be had after graduation. In radio broadcasting, that's been a chancy proposition at best for over twenty years, and it's been a cruel joke for the last five or ten. There are precious few jobs in radio, and the number seems to be perpetually shrinking every year. But then again, colleges have been doing that in many disciplines for years
and communications is no different.
