@billyjoebowers There's something even more fundamental than efficiency arguments.

It's that the profit incentive is a terrible proxy for desired outcomes and is primarily motivated to lobby government for self-furtherance.

Consider private prisons. They want more incarcerated and lobby for 3-strike laws and reduced oversight.

Meanwhile government prisons want fewer prisoners due to immutable oversight and may work inter-departmentally to use recidivism as a signal for remedial intervention.
