It's not that every psychological problem is directly due to capitalism (though many are directly or indirectly) it's that capitalist psychology mostly cares about profitable treatments, whether they're effective or not. I'm inclined to think some form of talk therapy or psychoanalysis may be more helpful to a lot of people than solely symptom-based treatment. But who can afford to go to therapy for years?

Even from the pharmaceutical side, we're mostly just tweaking the mechanisms of consciousness without necessarily addressing or understanding the holistic structure, so the best we can hope for is trying various meds until one sort of works. But most of us can't afford to spend years trying a new med every few months, with all the turbulence and uncertainty that goes along with it.

Cbt, dbt and the like are somewhat useful at treating certain symptoms, but generally fail to address root causes. And the way they're often applied, they seem more intent on teaching people to accept their treatment under capitalism than anything.
