The problem with radical restructuring, especially in higher ed, is that it rarely makes things better.
“Too many people in college” - I assume that you meant that there are people whose career choices do not require a college degree, so they shouldn’t be wasting their time and money on a college degree.
The big problem with this is that it plays into a class system, in which the “elite” go to college, and get all of the high paying “thinking” jobs, while the “lower classes” go to trade school and learn the lower paying manual jobs. This will compound over generations, as the people in lower paying jobs are unable to afford the education support that is available to high paid families, etc.
“Too many ridiculous majors” - there is a massive amount of literature on the benefits of an education which is rich in the humanities. Moreover, for far too many people “ridiculous” = “I don’t understand it”, or “it’s against my religion/ideology”. If you want to take an exaggerated example, I am sure that most flat-earthers think that astronomy is a ridiculous major. Even less exaggerated is that many fundamentalists (of multiple religions) think that paleontology and evolutionary biology are ridiculous majors.
College is about expanding your mind, and eliminating majors which you, or any other person, deems “ridiculous”, has the exact opposite effect. Once you only have majors which some specific group thinks are OK, you do not have a university, you have an institute of indoctrination.
That is why I rarely refer to any major as “ridiculous”, even when it seems to me to be so, at first glance. As an academic, I am aware of my own limitations at determining which majors are important or needed, and which are irrelevant or superfluous.
“Too much superfluous administrative fluff.” Yes and no. There are indeed too many high paid administrators. However, there are far too few mid and lower level administrators. Moreover, many administrators are there because of demands by parents and students. Look through the titles and what these people do, and you will see how many of them were created to make sure that the services which parents demand are provided.
The problems of universities is that they are either run by academics, who are not usually good at administration, or by professional administrators, who are unfamiliar with how institutes of higher education work best. Academics know what needs to be done, but are usually incapable of actually achieving this, while professional administrators don’t know what needs to be done, but are all too often very effective at getting the wrong things done.
Well, in all honesty, sometimes it’s difficult to get a good answer from an academic on what needs to be done, since academics are taught to question everything, especially their own ideas. This is great in education and research, less so when trying to develop policies and mission statements. Unfortunately, academics who are absolutely certain in their ideas are even worse…
