Profit in education? Really?
Yes, education is a business and a comodity these days, but they have to balance the books in order to retain the not-for-profit status with the feds, which most educational instituitions are. Regarding clinical faculty, many of them dont get paid, or get paid minimally, but hospitals will require payment to train students. Hospitals dont do much for free these days. When you mention a "group" of medical students trained for $500,000, what defines a "group" by your terms? If the group is defined as a class, then I'd be interested to see that data, for the cost of salary alone for 4 years for 10 preclinical professors which work for the school exceeds $500,000.
The economy has also ripped into schools endowments, if they even had any to begin with. Hence, these dollars which funded professorships and the like are being taken from elsewhere, namely tuition. An article on this is

On the other side of the coin, speaking of for-profit education: Did you know Kaplan is starting up a Law school? It's under application for accredidation now. This will start a new age in for-profit educational services. University of Phoenix, another for-profit "school", who I get like 5 spam emails from a friggin day, now has more students than Harvard, Yale, Princeton, Brown, Dartmouth, and Cornell, combined.
