Personality disorders virtually always involve others as an intrinsic part of the condition. Therefore, high positions in business is [sic] often an ideal forum for anyone with a personality disorder. In the field of business, such individuals are given sanction to act out various conflicts in an entirely insight-free way. Business truly is a sort of show business for the unattractive--the psychologically unattractive.
Perhaps this is part of the explanation for healthcare's woes; high positions in healthcare too often seem to be filled with non-medical persons who exercise their personality disorders in an insight-free manner.
