I think there's a u-shape here. Lots of jobs are disposable. Being the bartender at Chili's is not much different than being the bartender at Olive Garden. So there's lots of jobs on the low end where it's relatively easy to dump the job and get another. My intuition is that the middle has the hardest time, once you get enough job specialization and income.
