Why are psychiatrists crazy? do they like to manipulate everyone into taking tons of drugs so they can make lots of money?

They aren't: Perhaps you've had a bad experience, but most psychiatrists truly want to help.

No, they aren't.: Psychiatrist do not make more money by putting anyone on medication. The drug companies profit from that. Psychiatrists are trained in biopsychopharmacology. They use medications because these medications really are effective for some people. Depending on diagnosis, counseling, especially cognitive behavioral therapy or supportive therapy. is also very helpful.

A little history...: 2 phenomena converged: 1) The explosion of brain & psychopharmacology research over the past 3 generations & 2) the non-MD therapists taking over much of the talking therapy that psychiatrists had been providing, but they can’t write prescriptions (and shouldn’t in my view). So psychiatrists have perforce become clinical psychopharmacologists. It’s a natural evolution of the field.
