Sure. And my general attitude is that if my employer can replace me then they should, so I can do something more productive (where I will be harder to replace). And to state the obvious: when you run your work life like this for 20 years you get pretty hard to replace.
Look: It’s not that we disagree about how the world works, it’s that we give it a different emotional coloring. Yours sounds bitter and resentful to me.
