I found the article somewhat simplistic, myself, and its depiction of psychiatry something of a caricature - certainly in relation to how it's practiced where I live (Ireland). It might be more accurate elsewhere, where medicalisation of mental illness seems so rampant that there might be some justification for identifying psychiatry with the "individual defect theory" the author names. In most parts of Europe, though, psychiatrists do still refer patients for therapy - they don't only prescribe medication. Yes, they do have that power, and yes that is open to abuse, but that is some way from identifying the power and the abuse as if they were one.
