<p>Information technology saves money. It doesn't contribute to the rising costs. Computer registration and billing, online documentation that doesn't have to be photocopies etc etc.</p>
<p>Even the Powerpoint presentations and equipment in the classromm save the Prof from have to draw the same charts, diagrams, equations etc over and over again.</p>
<p>I graduated from college 35 years ago and I don't remember there being a dearth of courses on Africa, Asia, or South America. In fact I vividlt recall a political science course on North Africa where the Prof assigned some reading and said the next class we would talk about Libya and King Idris. The night before the class Gaddafi launched his coup and overthrew Idris. The Prof came in and said he had no idea what was going on or who this guy Gaddafi was and apparently neither did anyone at the State Department.</p>
<p>The costs go up because anything the school decides to spend money on is by definition necessary. That is the way all businesses work when the profit motive is removed. In other words they work just like government. A for profit business would avoid sectors where they could not make money. A college has no such motivation and so you get ersatz Indians teaching native American Studies for $100 grand a year in Colorado.</p>
