We go to psychiatrists as people used to go to priests, believing they have access to the truth, and with it the power to heal and absolve.
The main weakness of psychiatry is that it believes that the sickness lies in the individual and not in society, thereby taking the well adjusted as its norm for health. But inasmuch as society is sick, the well adjusted is pathologic. What then is psychiatry? A hidden police; a seemingly objective force working on behalf of the given order of power.
When psychiatry locates the problem solely in the individual and proceeds to treat him accordingly then it acts as an agent of repression on behalf of the powers dominating society and culture.
Psychiatry as a marketing tool; the tool that helps people to adjust themselves with the least amount of friction to their roles in the economic machine, while blinding their eyes to their own uniqueness and individuality; psychiatry as one arm of the powers at be.
