But if you're middle class the price has gone up and may be unaffordable.

My basic point was just the fact that the numbers we compare have nothing to do with each other. (The really don't.)

And the ratio of administrators to professors has also exploded.

The number of administrators, as traditionally defined, has changed little, though the number of professional staff has increased a lot. The biggest increase has been the growth of IT, though it goes beyond that. The part of this which is IT-related is somewhat mirrored by most other labor-intensive stuff.
