I'll just pick up on one piece of what you said, "meds from a psychologist." While I don't disagree that greed may be a part of it, unless that person's extra training involved a medical degree... that's truly been a crazy idea given the things that can go wrong even with "simple" medications, even when you know what questions to ask about other preexisting conditions and how to interpret the answers. The other thing…
I co-majored in a psychology and neurophysiology degree - psychologists should absolutely and totally be excused from meds prescribing. They do zero serious biochemistry, and often not even token biochemistry. Meds may need to be allowed to be prescribed by other professionals, but whoever it is should need to do some serious biochem training in some manner.
and pharmacology, and physiology, and several years on the wards watching the meds go in, watching the pee go out (or not), seeing what happens to the patient, sorting through laundry lists of meds at admission and discharge, losing arguments with pharmacy about why that max-concentrate K-Phos is a bad idea considering the patient's CCr was 1.1 yesterday and now it's 1.4, etc, etc.
