The nirvana fallacy is the informal fallacy of comparing actual things with unrealistic, idealized alternatives. It can also refer to the tendency to assume that there is a perfect solution to a particular problem. A closely related concept is the perfect solution fallacy.
The child protection service is quite simply a fallacy. ÀLL foster carers want to believe they are heroes. When in-fact they feed themselves from the money they earn from taking in children, based on paperwork. A transaction between an agent and corporation, with many parts.
The view that now pervades much public policy economics implicitly presents the relevant choice as between an ideal norm and an existing “imperfect” institutional arrangement. This nirvana approach differs considerably from a comparative institutionapproach in which the relevant choice is between alternative real institutional arrangements (wikipedia.org)
