+1. I've come to hold this stance as well. I'd go a step further and suggest the lack of job mobility and variety benefits no one at all and actually hurts society a great deal, because it leads to the infamous peter principle, where people move up the career ladder until they reach incompetence, at which point they do everything they can to stay there because moving would mean reduced pay, reduced status and a feeling of personal failure. The number of people who've long lost any enthusiasm for their work and yet won't give up their seat because they don't know how to do anything else is also quite frustrating and counter productive. Ah well :)
