This seems more like a social commentary about job satisfaction for the career at almost 80%, but I suspect the pattern of movement that the “only way to get a significant salary upgrade is to switch jobs” is the secret pressure. There are a LOT of disincentives to moving right now, especially with coast housing stock being at record cost and such low levels. Add to the fact that employers seem to be having a great time laying everyone off, and you have a powder keg for dissatisfaction.
