I went to a publicly funded mental health clinic after my breakdown, arty. While I was there, I had an excellent doctor - who had been in the game for years and years. I literally went in at one point - asked for anti-seizure meds and Klonopin to treat anxiety and he talked me out of the latter, telling me I didn't need it and to just find off the anxiety with a walk since it wasn't really real. He actually looked a little disturbed that I asked for Klonopin at all - he said that it was way over marketted and was equivalent to a street drug. 

He was extremely level headed, intelligent and could read between the lines. Juxtaposed with him, I still have access to a private doc who I know would give me anything - literally anything - if I had the right money.

I'm not so sure anymore about the idea you'll be getting "bottom of the barrell" just because it is state funded. That sort of thinking is the result of libertarians and profit motive folks. State institutions would be reliant on tax dollars and would probably end up being given the evil eye way more than these big corporations ever would.

SSRIs are antidepressants - they don't treat psychosis. I don't know anything about antipsychotics. So let's not blur those together. SSRIs are very bad medicine - doctors say they literally don't know how they work and they have all sorts of scary warnings like "homicidal ideation." I think that their existence is actually the result of deregulation - of making medicine way too much of a business instead of a service.

Mental health treatment has become a commercial thing and, thus, is more concerned with having more clients than more cures. This got worse in the 90s, I think, when we got rid of regulations of medication that had already been there. SSRIs like Zoloft, Effexor, etc. don't exist to treat serious mental illness - they exist as the equivalent of snake oil supplements to cure a case of the blues. If people are writing articles like what you have posted, we may bring those regulations back.
