The problem with Grad School, is that it is often designed for the narrowly focused individuals who can think brilliantly in their little box. Unfortunately for them, that little box isn't representative of the world at large. This is what makes many of them unemployable. Unless the job calls for narrow focus and a published paper as the end goal, there are often bachelor level graduates who will be able to perform the same function for less wage and with more situational awareness necessary to get a project to completion. The best part, if the person isn't working out, there are 100's, of not 1000's, waiting in the wings for their chance, as opposed to one of the much fewer masters or doctoral grads who weren't good enough to get on as a post-doc or adjunct professor so they could continue with the research they really would rather be doing.
