I'd be careful with this assertion. I feel comfortable walking away from a job but I've worked with plenty of people who feared adverse impact on their loved ones if they gave up the income + benefits that they provided to their family etc. via the stagnant job. Individuals are embedded in structures that don't always make room for every individual choice. I try to always err on the side of the other person having a good reason to be where/who they are and thus the individual dignity involved (if not automatically respecting always the actions that an individual might take.)
