That they can, that they must, that they always, or that there are any circumstances under which they could?
Obviously the idea that private hospitals always offer better value would never have been entertained by anyone.
Equally, nobody in possession of a mind worth inhabiting would be so stupid as to infer from this story that private hospitals cannot offer better value.
And better value than what? Surely it goes without saying that some must offer better value than others?
Any hospital that doesn't kill too many patients is better value than one that does - a category which has often included non private hospitals.
I'm struggling to see what idea has been killed here.
