It is something to be ashamed of for employees to leave their employers? Where? I've worked in a few places in the US and I never sensed any "shame" when an employee left. I have sensed that employers feel shame when laying people off though.

I think the modern wage labor relation is very different than medieval serfdom, on both sides. Marx does a good job of explaining this Kaptial Vol. I. What is the same is the basic exploitation that underlies that relationship.

I agree 100% with the rest of what you say though, there are too many people taking BS jobs too seriously.
