One of the purposes of the planned inefficiencies of state services, often the direct consequence of completely economically irrational private-public partnerships and offloading to private firms of public services who will bid for contracts to run state-constructed infastructure on the basis that they will minimize costs (inducing low wages, high turnover rates of workers and low efficiency, surprise suprise). The malignant genius of it is that the inefficiency of the effects of partial and shadow privatization of what should be public services turns people against them and pro privatization because they still perceive it as public.
A similar phenomenon can be seen in the case of tax systems, especially the US tax system, or the US postal service.
