"Personally, I liked the university. They gave us money and facilities, we didn't have to produce anything! You've never been out of college! You don't know what it's like out there! I've worked in the private sector. They expect results."
Dr. Ray Stantz (Dan Aykroyd)
Ghostbusters, 1984
Don't jump to the conclusion that universities are havens for slackers. Even fairly mediocre universities now require professors to publish a certain amount of work to be given tenure. This can be stressful, on top of teaching three courses and doing often time-consuming committee work. Some professors stop researching when they do get tenure, but most continue to publish research -- both because they like to do research (you become a college prof because you're totally into the subject you specialize in), and because you don't get as big of pay increases if you aren't productive. (And you want to be promoted to full professor, too.)
