Generally you're probably right, but people do get stuck in jobs for real because of external constraints. A mortgage is not always one of them because it usually means you have capital to trade for your mental health.
Divorce, Healthcare needs, Child Support, Immigration Issues, are the kinds of thing that can leave people genuinely stuck. Not to mention the possibility of not being able to get a good reference because of being burned out.
Obviously, it's up to each person to avoid these kinds of trap, but they do exist and they do damage what could otherwise be productive lives.
