The pressure to reduce health care costs is aimed only at the treatment of real diseases. There is no pressure to reduce the costs of treating fictitious diseases. On the contrary, there is pressure to define ever more types of undesirable behaviors as mental disorders or addictions and to spend ever more tax dollars on developing new psychiatric diagnoses and facilities for storing and treating the victims of such diseases, whose members now include alcoholics, drug abusers, smokers, overeaters, self-starvers, gamblers, etc.
