Besides, most of these sorts of private/public relationships are unlike other true markets anyway with very little competition and only one customer to appease. We end up with a system with even more opaque responsibility/liability chains and encourage crony business deals.
Without any discernible benefit for the private nature and creating negative incentives that encourage more violence by correlating the success of an industry on the greater imprisonment of people, I can’t see any net-benefit for them to exist.
I tend to be a fan of markets in a practical sense but I wish we had clearer distinctions between these public/private operations that are spun as being more “efficient”. Plus a ton of people use these failures of public/private organizations to disparage markets. So it’s not doing anyone any favours to support these half baked pseudo market arrangements, even if you are pro market. In most situations we need purely public or market solutions. I’ve seen few examples of mixing the two that left us better off (the US health insurance ‘market’ is the shining example).
