I do agree with you about balance and burn out. However, this references a study on social workers, many of whom are not therapists. I'm not sure what the numbers are exactly, but I don't see that the majority of social workers are even therapists. Social workers do advocacy work, work with children in the courts, hospitals, coordinate volunteer services, help homeless populations, etc. They are usually VERY underpaid in comparison to therapists.

The survey isn't available online, unfortunately. But an article that references it states that the same levels of burnout have been found in other occupations too, and that some social worker studies show they have less burnout than those working in other occupations.

I'm not sure if that article applies much to social worker therapists, though I can imagine some experience burnout, such as those working in community agencies. There is a lot of burnout in primary care that is concerning.
