Salaam,
OKay brother I need to educate you a little here. I just finished my Psych rotation and am somewhat sensitive about this. When you work with profoundly mentally ill people and see the devastating effects of psychosis up front then it tends to knock you off your ivory tower.
People with schizophrenia are so disabled by hearing voices, seeing hallucinations, and basically just so disfunctional that they cannot get or keep employment. Aside from the disruption of basic abilities like feeding, clothing and washing oneself there is also the stigma society attaches to the mentally ill. These people have a neurological problem with the dopamine receptors in the brain, they are over sensitive to dopamine or produce too much. The meds work by blocking some of the receptors and then the person's symptoms get better.
However these patients are notorious for noncompliance and almost always stop their meds once released again. They feel "better" so they think they do not need their meds anymore. So in about a few weeks they come back through the ER screaming, crying, so very afraid or aggresive and in some cases they've tried attacking people. So we once again start their meds and keep them in the hospital until they are not a threat to themselve and others. Then by law they must be released again.
Since they cannot work our govenment pays disability for them. They make sure they have enough money for food, housing and their psych drugs are covered as well by state funds. Would you rather us leave them unsupported and unmedicated? How cruel and heartless. I strongly suggest you work in a place for the mentally ill before making such quick judgement on why psych drugs are being paid for by the govenment. Things tend to be seen in a different light when you see mental illness up close and personal.
