My favorite econ professor at my (private) university often pointed out that our eventual diploma was far more about signaling qualifications rather than education; that you won't necessarily get a better education than at the state school down the road, but it proves you can play the game; get the good grades in secondary school, do the things you need to do to get into the university, get the grades, do the work. It's far less about what you actually learn or the 'quality' of the education, whatever that means.
