Big pharma is evil; I would agree with that premise. But because people don’t understand exactly how big pharma is evil, their anger gets diverted away from valid criticisms—its role in distorting data, for example, or withholding lifesaving AIDS drugs from the developing world—and channeled into infantile fantasies. “Big pharma is evil,” goes the line of reasoning; “therefore homeopathy works and the MMR vaccine causes autism.” This is probably not helpful.
