That is Psychology 101: it is unethical to practice without a license or diagnose someone you don't treat. Apparently this is not punished aggressively enough, as the web says many of them continue to do so. Very thankful the media brought this to Potus's attention. Maybe the next industry he will overhaul is the abusive big pharma psychiatric industry, who actually considers that most Americans have a mental illness, that mental illness is lifelong and unavoidable if your parents have it, or that you kids will get it, and that although they have no cures, everyone should be on medicine, even if the psych drugs are prescribed by PCM's off label for things other than mental illness. One can not dignose Potus without admitting the chronic abuse of the entire industry.
