I don’t disagree with what you’ve said here entirely. Capitalism absolutely aggravates mental illness and it produces conditions that generate mental ill health.

But ascertaining the correct etiology of a condition doesn’t necessarily have an impact on the treatment. Say a person is experiencing liver failure due to alcoholism. The cause is alcoholism, the condition is liver failure, and yet the treatment remains the same whether or not it was alcoholism that brought about the condition.

In the same way, we can attribute much of psychiatric disorders to capitalism but, at least for the individual, the treatment remains the same.

I think we need to be cautious to avoid a puritanical attitude towards psychiatric meds. I could write a book based on my criticisms of psychiatry and the pharmaceutical industry and how they operate, however at the same time we shouldn’t discourage people from the appropriate use of medications to improve their wellbeing regardless of how ruthless and exploitative the pharmaceutical industry itself is. The system is going to be fucked whether or not someone has an appropriate medication regime for their mental health. The only difference is that one option means an improved quality of life.

It’s also important to keep in mind though that there are certain mental illnesses that do require an ongoing medication regime for maintenance and that this would persist under socialism. Schizophrenia and bipolar are two very obvious examples here. Even under fully automated luxury gay space communism, the overwhelming majority of cases of bipolar and schizophrenia are going to require ongoing medication regimes.
