Every single time I see this type of conversation come up it's always about the more privileged higher paying white collar work.
In my shit experience, blue collar work is "get shit raises or take massive pay cuts." There is no "change job and also make more." I've been stuck in the same cycle for 15 years now... Every time I leave a job I get knocked back to the wage I made when I first started the job I left regardless of the new position.
But that's because only white collar workers are seen as people. Us blue collar workers are just meat machines that never deserve more than we were "bought" for and any new employee is automatically assumed to be as intelligent and skilled as a dead cockroach.
