How much of that is the fault of colleges? All that shit about requiring science majors to take liberal arts classes or art majors taking calculus to make them "well rounded." A bachelor's degree is supposed to be a mark that you're just all around better educated than someone with a mere high school diploma, to the point that "It doesn't matter what you major in, just get a degree" is somehow valid advice. But a doctorate is awarded for a significant work of original research; a Ph. D. means you're the world's foremost expert in some tiny corner of a sub-discipline, kind of the opposite of being "well rounded."
