This is where I think academia has got it right. When you do something, you get full credit on it -- your name on the paper, your face on the book and department website, you're the one giving the presentation, you're the one who gets the benefits if it's commercialized (after the university takes its cut). Loyalty also is valued (or a less negative word to use is being a team player), as people write recommendation letters for each other and their reputation is at stake when they do anything.
