Taxpayer funding has been cut significantly, which according to at least one study correlates strongly with the increase in tuition costs. Do you have evidence that the number of administrators indeed increased [EDIT: as much as you say, and that what the admins do isn't valuable] and that it significantly affects tuition? I'm tired of this easy, baseless claim, in every field, that people don't need to pay taxes and contribute to society, they can have a magical free ride by cutting mythical waste. In fact, say some, we don't even need many colleges; these kids can just be plumbers. Meanwhile, the #1 determinant of college attendance is not academic ability or achievement, but parental wealth. College attendance dropped ~200,000 last year; the country is going backward.
