I attended a small but well-known liberal arts school that increased tuition about 20k in well under a decade.

In a single year the tuition increased 5k, and yet the department of my major was downsized and classes that I needed to complete my degree were full. At the same time though they built a new $42 million "cultural exchange" building and began adding an enormous sports facility. It turned out that actually there was no intended purpose for the new building either, and it was mostly sat empty as far as I know.
