UNCIOR does CAD work for McDonalds remodels and such. You are paid more working UNICOR (sometimes over $100 a month). I did CAD in college but I sure as hell am not using my education to make the Warden/Cops a fat bonus. Lots of guys did it though, especially those with no savings or people. It becomes...interesting when your boss is also your prison guard, and your boss' bonus is tied to performance metrics.
