I went to university in 2008. We did not have dorms with AC. The dorm I lived in was built in the 40s or 50s. Tuition (no relation to dorm costs) was still rising rapidly. Now my alma mater has new dorms with AC, but they cost far more than the older dorms (which are still available). Tuition has continued to rise since then, albeit more gradually.

My university did not provide free medical care. Professor quality has not quantifiably improved over that time.

Have sports team costs increased so rapidly in the last 10-15 years?
