“Just switch jobs” is such an entitled attitude. There are so many reasons people can’t just change. So many employers who can’t or won’t negotiate.
Fuck off.
Even if you are able to change jobs, your current employer is still extracting more productivity from you than they are compensating you for until you do change jobs … into another position where your next employer is still extracting more productivity from you than they are compensating you for, but maybe not quite as badly as the last one, so you “feel better.”
You’re still getting fucked either way, because capitalism.
