Well, I can tell you that an instructor/teacher/prof that actually cares and strives to be creative and actually teach is of massive value. I had only one in my time in college that was worth much of anything. It still blows my mind how teachers can take things as interesting as history and economics and make them so unbearable to learn. 

I sometimes wonder why I'm even doing this.  But individually, it's very rational (nice hours, good pension, etc.)
