Liberal arts are easy. People who could not do any real job, get tenure in liberal arts and milk the system forever. All they do is “educate” few similar useless types!
This Mr. Davis is right. Colleges need to educate for real life jobs! Get rid of at least half of the liberal arts professors would be good start.
In fact, done properly, they're not easy at all. Classical philology, stylometric analysis, genuine historical research, or just finding some thing new but interesting and justified about any topic of research in the humanities is hard work.
The problem is that the academic departments have replaced genuine learning with political indoctrination to such an extent that there was probably more genuine research in some humanities fields in the Soviet Union than there currently is in the US.
BTW, the Greeks had a name for the class of persons who were solely concerned with having to work for a living: slaves.
