When you write "needs improvement" I think "need a complete overhaul" would be better.
Other people in this thread have already mentioned the drugging of children but I'd like to stress something else.
You compare psychiatrists to chiropractors as far as legitimacy is concerned, but there is a very big difference.
No one can force someone to see a chiropractor and that chiropractor can't strip you of every civil right without an accusation or a trial based on his assessment.
A psychiatrist can and does that on a regular basis.
This is a huge difference.
So yes, the profession is BS but I would say the pendulum has swung a bit too far based on the help we were asking for and didn't get.
A hard balance for sure.
How did the situation develop?
What happened to your friend?
Sucks to be American, I guess. Here we have human rights laws which protect people with mental illness.

Don't go there. The situation is almost global with a few legal nuances that barely have any practical impact.
Since you're mentioning the ECHR, have a look at the German man that was involuntarily committed and drugged for years just because he said his wife was engaged in a large financial fraud.
Spoiler: she really was.
Protections in the UK for mental illness are reasonably strong. (Much worse for people with learning disability, but psychiatrists tend not to be involved so much in the worst abuses there.)
"AIDS? Sucks to be African, I guess. Here we use protection."
Edit:
OK. I've read your Bio (stating that you only follow mental health related handles) and I've also read you twitter feed. It reads like a propaganda piece. It would be funny were it not for the seriousness of the subject.
You are anything but unbiased and have a large interest in maintaining the status quo therefore the baseless "ignorant" insult.
Honestly, just from personal experience, the profession seems to be marginally above chiropractors in legitimacy. Diagnosis and treatment is inconsistent and arbitrary - varying widely from practitioner to practitioner. Treatments are prescribed with "guess and check" methodologies. Longitudinal effects of many treatments aren't even known and results of many which have been eventually studied aren't good.
I recognize a lot of people have net positive experiences but the profession and pharmaceutical industry surrounding it 'needs improvement'.
