As a matter of fact, I have some in-depth observations on the business model of private schools through out US. They may be diversified in the most superficial layer, but deep down to the bottom, there is a common line: money. It is not anybody's fault but they cannot survive without it since they do not have the mandatory public tax sytem to support them, and utilitarianism is essential for anyone to survive in private sectors.
