I don't think your first point very well thought out.
Any doctor (or mechanic, accountant, etc...) could benefit by providing false/sub-standard services to keep the client returning regularly.
As for the measurement, it's almost entirely based on feedback from the patient.
I can see how a depressed or mentally ill person could be more susceptible to accepting medication that wasn't in their best interest, but that problem seems intrinsic to all medication.
Wrong. Doctors would (hopefully) lose licenses and have big legal consequences. Mechanics are also subject to some form of objective measurement as even the average driver has some sense if a problem is being fixed or not.
But psychiatry? Forget it. You pay to talk to someone, they have a nice couch, soothing voice, make you feel good for an hour, but nothing really changes. But hey, I liked that hour, I should keep coming back!
