This still isn't good logic. You can't take one case of one doctor faking literature and argue that its a widespread problem.
I am very left-leaning (if you don't recognize my avatar, look into Noam Chomsky, he's my hero) and I agree that corporate interest in many facets of our lives takes precedence over values like human rights. I agree that pharmaceutical companies are looking to maximize profits above other considerations (see me-too drugs, look at money spent on direct-to-consumer advertisements, etc.) but that does not mean that all of psychiatry is worthless.
Companies are copying other profitable drugs so we have redundancy, drugs are pushed onto the market without demonstrating efficacy over other drugs already out and many other abuses, however there is still a lot of sound evidence that psychiatric medications can be very useful and necessary for many people's quality of life.
Lastly, you shouldn't put your "faith" into doctors, drugs, religion, or anything else if you honestly want to seek truth. Look at the available evidence and think critically.
