This is not bringing "efficiencies" of private business to the government sector, which is a all a big myth anyway. To the extent that private business is efficient it is driven their by profit motives and the competition of the free market. There is no competition in monopolies government monopolies granted to private companies except the initial sale price (the cost of lobbying and paying off politicians and officials).
With a monopoly the profit incentive is to drive up the cost to the user. Now suppose the terms of the charter are fixed profit on revenue - then the incentive is to drive up revenue - i.e. costs on the user. Efficient use of resources has nothing to do with this.
Like privately operated prisons - the incentive is to maximize prisoners x costs per prisoner. Those are not public goals.
Our founders, our constitution is built on the basis of the recognition that there are public goods that belong to everyone, and the government is there for the people.
I cannot believe that this kind of a diatribe is necessary against anyone on THIS forum of all places in the universe.
Except if the private service provider does not provide a quality service then they lose the contract. Most toll roads are awarded by contract to provide a service. Don’t perform and the contract goes out for reb-bid.
Private prisons are not except from government standards and laws. If they violate those laws or standards they lose the contract AND may be prosecuted criminally.
