People with longer tenures are different because they are motivated by something other than compensation. Perhaps it's the desire to build bigger things that will take more than a few years to complete, or maybe the sense of ownership in making the long tail of product refinements as opposed to leaving behind products that are "mostly done". I suspect it's mostly personality differences that lead to the difference in motivation and thus longer tenures, and not so much the reverse where longer tenures causes different personalities.
