I think this old post at Photon Courier helps explain why academic experts made such a hash of things. It's all about the theory
They Had a Dream
Rule by experts comes a cropper
They had a dream. For almost a hundred years now, the famed academic-artistic-and-punditry industrial complex has dreamed of a government run by their kind of people (i.e., nature’s noblemen), whose intelligence, wit, and refined sensibilities would bring us a heaven on earth. Their keen intellects would cut through the clutter as mere mortals’ couldn’t. They would lift up the wretched, oppressed by cruel forces. Above all, they would counter the greed of the merchants, the limited views of the business community, and the ignorance of the conformist and dim middle class.
In university humanities departments, theory is increasingly dominant--not theory in the traditional scholarly and scientific sense of a tentative conceptual model, always subject to revision, but theory in the sense of an almost religious doctrine, accepted on the basis of assertion and authority. To quote Professor "X" once again: "Graduate "education" in a humanities discipline like English seems to be primarily about indoctrination and self-replication."...
Becoming an alcolyte of some all-encompassing theory can spare you from the effort of learning about anything else. For example: if everything is about (for example) power relationships--all literature, all history, all science, even all mathematics--you don't need to actually learn much about medieval poetry, or about the Second Law of thermodynamics, or about isolationism in the 1930s. You can look smugly down on those poor drudges who do study such things, while enjoying "that intellectual sweep of comprehension known only to adolescents, psychopaths and college professors" (the phrase is from Andrew Klavan's unusual novel True Crime.)
