This is long, rambling, and rather personal... Take it for what it is worth.
I went through a similar stage where I explored society's perception of a "higher education." Ended up as 30 some odd pages of notes and a heck of a lot of mental growth on my behalf.
It started as an exploration of what I aimed to achieve with graduate school. I was immensely unhappy with my undergraduate education, and set out to establish exactly what I sought from my proposed post-grad studies. I dealt with various topics such as: the search for "Better" education, and what "Better" really entailed as far as school rankings... Obtaining an education for the right reasons... Society's expectations for what such an education entails in regards to higher education vs Career preparation --> what that really means, similarities/differences etc..
It snowballed from there into a rather existential search for purpose and what I aimed to do with myself. The problem most often present in today's society is that students view university studies as a "next step" in life, rather than something that should be done for the sake of bettering one's self. Again, the career preparation and getting an education so that "you can get a good career" versus going for the sake of gaining an education for the what I'd consider to be genuine personal growth.
The entire thing went rather philosophical, and I established what I considered to be the wrong reasons for pursuing an education. Next logical step was to ask myself what exactly the right reasons were. To somewhat borrow from what I'd written...
Humans have no assigned purpose in life. There is no mandate from a creator specifying the "correct" way to live our lives (in regards to overall purpose.) This is largely self-determined, and varies widely amongst the population. Many situations impose outside needs upon us, and give many people a "purpose." Having children, for example, necessitates that an individual find a way to provide for said children. Be it an evolutionary urge to ensure success and survival of your offspring, this is somewhat difficult to ignore...
But beyond such needs imposed upon us by society (IE: Taxes), as well as sustenance and so on, what is our purpose? Our raison d'etre? Given the infinite number of directions possible, where does one take their life? As much as we ask ourselves that question, however, at the end of the day, that direction is largely irrelevant. An argument can be made toward utilitarian vocations, but our destinies are largely free for us to decide.
We either choose to live passively or actively within our greater society. A passive lifestyle follows the traditional expectations of society; assimilation to cultural norms and following the path of least resistance is almost expected. Anybody who hits 25 will tell you the shift in perception that seemingly hits you like a freight train. Get a house, get married, have your kids and a dog ETC. It may not be mentioned, but deviation from the aforementioned list results in somewhat of a sense of guilt and feelings of a lack of "success." The world controls you, rather than you it. No problems are presented when the plan is followed, but you've accepted social dominion over your life.
Cue the Higher Education. Without it, we fail to gain a true understanding of the world in which we live. We are ill equipped to mold it into a shape which we find desirable. A real education isn't about career preparation - if that's what you had in mind, then you're there for the wrong reasons. Robert Pirsig touches on this subject in "Zen and the Art of Motorcycle Maintenance", a fantastic philosophy book if there ever was one.
In the opinion that I finally arrived at, an education should give you the tools to assist us in the search of truth. I'm talking about pure unbiased absolute truth, if there ever was such a thing. "The marriage of logic, reason, and creativity in an attempt to truly understand ourselves and the reality we live in." That's the big one, to me... If an education can help you to shape your mind into one that aims to see the truth of something for what it honestly is, then you have succeeded. The area of study does not really matter, be it any of the sciences or the arts. That freedom requires absolutely nothing from you, and should be the end result of everything that you do with your life. Eliminating bias is single handedly responsible for mankind's salvation, and the distortion of truth solely responsible for our downfall.
If that's the end result of your education, you've done well for yourself. At this point, the world is much like a wrapped gift, waiting to be discovered. What's under the gift never changes - you simply exist to correctly discover what's underneath. It isn't about the salary or perceived level of "success"... Just work your *** of and learn what you can of your subject, but learn it for the right reasons. Learn it for the sake of learning. If academic excellence is your goal, the grades and everything else will follow.
Don't get caught up in the game. If you can avoid that, you'll be alright. If you're working your *** off, you'll be very employable. Just make sure you're working your *** off for the right reasons.
