Excellent post CopperMoon

I feel much the same way, your points are on target.
The issue at hand is a power issue.
IMO, when a person poses an immediate danger to himself or others beyond a reasonable doubt forced treatment should be option*. However that has always been subject to abuse by profit hungry intuitions. Any intuition with less than perfect intention can declare everyone that drops by as an imminent threat even if they are not. But by doing so that opens the door for professional services, services which require someone to pay. Insurance, state, ect... money comes in and the more people are committed the more profit. This has been the modus operandi for most Psych hospitals in the past, even many to this day no matter how much people deny it. It is exactly this mentality that has destroyed mental health care in the United States if not around the world. Today this mentality has moved from hospitals to big pharma, where the system is rigged to guarantee a diagnosis that can only be treated with psychotropic drugs.
Having such power to force treatment on anyone no questions asked creates another, perhaps even bigger problem. The treatment itself. Patients no longer have any power, which strips them of all rights. Because such power held by institutions will always assure a fresh supply of patients, it does not matter any more if treatment even works. One could even say "well, there all so dangerous, better here then on the streets". Psych hospitals then them turn into prisons where mistakes are not held accountable to anyone or anything. Its even better for institutions not to invest less in treatment because that in tern maximizes profit. And poor treatment will not interfere with offering forcing more services on people. Good well meaning staff start to leave and those who take over can be anyone with any intentions. No accountability, unlimited power with little to invest in patients leads to appalling, abusive, inhuman environments. Patients are terrorized at no fault of there own. The people who treat them like animals do so because the objective is profit, not a warm feel good mission statement. Further, a risk opens up for the control of people who do not meet societal norms, since they to can be declared dangerous with a doctor's pen. You now have a beast running unchecked.
When institutions get to this level they no longer do good, they don't even help, rather they begin to do damage. People who go through the system become sicker, they become bitter, they learn hate. Their lives become destroyed, shattered, in grief. This sets off a chain reaction of events that ripple through society. The mentally ill then start to become a burden on society; they begin to resent authority (because the only authority that promised to help betrayed them with abuse) taking that anger out on society. Property, people, you name it. Their decline means even more need for help, forcing society to take the cost to a much deeper level.
Eventually patients begin revolting against the system. Institutions are no longer respected or taken seriously. Insurance companies no longer want to pay. The system is viewed in disgust, and I don't blame anyone who does. Even when a person is in danger no one can do anything because the pendulum has swung in the other direction. The system falls apart, yet remains grossly incompetent.
In a nut shell this sums up what has happened overtime to mental health care system.
Where are the mentally ill toady? No place better. Homeless or in prison. Prison certainly isn't a human place for them, neither is being homeless. They still are not getting the help they need.
Id even go on a leap saying some of those psychopaths in society were created by those very same institutions. The amount of foster kids that under go mental treatment is just frightening. I have seen kids in this type of care, and I don't want to get into it.
* Where a person is forcibly committed, they should loose little if any rights. They must have the right to be treated like a human being. They have the right to exceptional treatment, dignity, liberty, respect, comfort, you name it in their benefit and no less. Just the way a criminal has Maranda rights, proof of a crime beyond a reasonable doubt, right to an attorney, evidence, a warrant signed by a judge, ect ect so should a person in forced treatment and then some.
Without a doubt if everyone had been treated like a human during a forced hospitalization we wouldn't be seeing half the posters that we do in anti-psych. Certainly not that hurt, bitter or angry. Every hurt person is a cost on society. Every hurt person is a victim. IMO everyone on here, anyone harmed or failed by psychiatry has the right to feel the way they do and for exceptionally good reasons. Its a normal reaction. That's sanity, not insanity. Everyone deserve the right to be treated like a human being, no less.
