This article from Live Science points to the impact of economic incentives on mental health treatment.
Psychiatrists are trained to treat people with drugs, but also with therapy.
The shrinks make more money by seeing more patients. Psychotherapy takes time and thus reduces the actual number of patients seen.
Insurance companies make matters worse for patients (and provide further disincentives to shrinks) by refusing to pay for "talk therapy".
There are talk therapies that are 90% effective at treating some disorders, but those are disfavored because talk therapy "takes too long."
See my point about our health care system incentive-izing the wrong things?
This is yet another example of how our health care system is broken and rewards the wrong things.
