I beleive it is a scam. Every single person I've met who suffered from "depression" had a troubled past, and often a troubled present.

Not saying the symptoms are mild. It's a nasty state to be in. Inability to sleep and concentrate, leading to all sort of physical issues and impossibility to learn and keep a job.

All that being said, the causes are rather clear. Hard to fix. All these pshyco active treatments are judge bandades, anything to keep the brain quiet which in my opinion often aggregates the issue. Dependence, side effects... A person is not depressed but doesn't have its full brain capacity.

It would be valuable if clinical consultants converted to social workers to help patients address the root causes instead of prescribing medications and whatnot. Thing is, it doesn't sell that well and isn't covered by your insurance. Medics and therapy sessions are.
