Have you ever been involved in interviewing any of these "experts" for entry-level positions? It is amazing how incompetent and uneducated (in their chosen field) someone can be and still graduate university. With good marks even.
It is possible if the school they graduated from is bad, but even then the point still stands and is even stronger: if they've graduated, they still are better than naive, unschooled individuals who are even worse in educating others. They at least have _some_ idea of the concepts involved.
