For professional educators (and perhaps some politicians), the purpose of education may be to create people like themselves.
In economic terms, the purpose of university education is to enable the recipient to earn enough (extra) to repay the student loan.
But according to the slogan of this blog, the purpose of education is what it does. And what university education actually achieves, much of the time, is widespread dissatisfaction and bad feeling. Not to mention superiority, envy, self-doubt, guilt, arrogance, pride. (For evidence of this proposition, look at some of the politicians who went to university themselves.)
