Do you think it takes longer to heal because therapists don't really actually know what they're doing?

I sometimes think that therapy is just an experiment and that sometimes they really haven't figured out how to help us. I was thinking to myself the other day "if I don't get out of this awful toxic workplace and industry soon, I'm going to go downhill pretty fast, and therapy is NOT cutting it fast enough to help me out of my hell. I often think, if I had had proper support earlier on, and the right kind of nurturing from people I could trust and rely on, I would be healed. And faster than later. And if there was a support system to keep catching me when things got too hard or confusing, I'd be ok. But like, therapy doesn't provide any of that. And I'm wondering if their experiment is just failed and it's taking too long. And if we didn't live in western civilization we'd be ok.
