The bigger problem is that those people DON'T treat mental illness. Instead:
- They ignore the raving lunatics until their actions land them in jail. At that point, they medicate them into compliance.
- They use the time freed up to work with people who are MENTALLY perfect normal. Their problems fall into 2 groups - those whose family are nuts, and those whose problems stem from spiritual emptiness, and the choices (mostly bad) that they have made.
