I think one good side of the argument is posted here, and I am concerned with how widespread psychiatric disability is becoming myself. On the other hand, especially when you lump in personality disorders...
Work can be a great place to get experiential learning for those who can get and hold a job. Still, in order to get work you need to:
-Transport yourself to work
-Show up to work on time, consistently
-Be bearable enough to avoid getting fired
-Be able to meet minimal performance standards (drawing on attention, memory, executive functioning, etc.)
-Avoid acting out that will make getting a future job even harder, or land a criminal charge (threats, destruction of property, substance abuse at work, etc.)
The patient's wanting employment does not guarantee that an employer will hire them, and not every personality disordered patient is in an appropriate place to get a job at any given time. If they cannot get a job, then a slide into homelessness, food insecurity, etc etc. may not provide optimal social conditions for recovery. The problem is, once the help starts coming where do you from promoting recovery into fostering dependence? When is withholding money, and potentially food and shelter, a motivator and when is it a callous affirmation that indeed no one does care about them? I don't think there is a straightforward answer, but it is an issue that could use more open and thoughtful discussion (and research?).
