School, despite opinions to the contrary, is a place or situation wherein those who desire to learn are afforded the opportunity to do so.
The question isn't "what can a school teach me?", it's "what can I learn there?"
My wife is earning a doctoral degree at UoP and she is decidedly NOT "buying a diploma."
She works very, very hard to write in the ASA style and complete each assignment to the best of her ability.
UoP instructors give no quarter, and those who fail to tow the line, fail.
We have witnessed many learners drop out because the curriculum is simply too difficult.
As to the person who intimated that schools which make a profit are somehow less scholarly than the "free" public universities might do well to study some economics, and not just Keynesian, but the monetarist (or Austrian) school as well, i.e., Friedrich August von Hayek.
