This has essentially become a subjective debate over how to live one's best life. Yes, many of us prefer freedom over financials.
However, very often in reality, at the heart of the argument that one has to just hang on and suffer well with their job is an insecurity that one doesn't deserve better.
To mental health professionals, I assume they would understand that the people looking for advice and reading their articles are from emotionally/physically/economically insecure environments, from which the advice "suffer well" is essentially entirely non-productive because it is their lack of a feeling of security that prevents them from knowing they deserve better. From the lack of security, which causes the lack of the knowledge that they deserve better, these people will typically not ever try to come up with a way out of their abuse until they hit rock bottom.
It's not that that's inherently a worse way to live, but the reason behind this way of living is typically (but not always) due to hidden insecurities, which abusive bosses freaking love to exploit because it's works very well at controlling their insecure employees. Yes someone can be secure and live like this but I think many would agree that this is a rare scenario and not the best advice for the average person looking at these articles.
