### Comment:
If that person is happy with their job, does it matter? Some people are perfectly content working for one employer for most of their career. Not everyone likes to change jobs every few years, especially if they have families and a new job would need a relocation.

### REPLY:
The point wasn't about liking or disliking a job. It was about how the guy working the same job for twenty years is likely making a fraction of what he could've if he jumped around a bit.
