Any psychotherapist, and mainly psychiatrists, tries to create a heavy dependence to their patents, not so chemical but behavioral and psychological, which they call patient bonding. They don't want to instruct the patient and make them independent. It's shown that this causes a consistent improvement and simultaneously establishes their dominance long-term.

If we had effective treatment, then psychiatrists that are effective would quickly displace ones that keep you hooked on non-effective ones.
