Universities, as most people know, are hierarchies -- caste systems based in part on whether you've attained the dire-sounding "terminal degree" in your field -- usually the Ph.D. It takes eight or ten years beyond high school for most people to get a Ph.D., and at the end of it, usually they've produced the notorious dissertation that's supposed to be the biggest hurdle of academic achievement -- a book-length research or scholarly project. All this, obviously, is a major life commitment. And if and when they get a job -- no small feat these days -- they're subjected to another long series of hurdles, often mediated by geezers long past their productive years, many of whom have become embittered, pointlessly pompous and sadistic. It all seems far from the ideal many of us cherished about "higher education." It's not an easy life.
