In The Guardian:

The examples of this are everywhere, but take as the most pressing the case of the NHS. “How can millions of people have benefited from the NHS and not be on the streets to defend it? Come on. The NHS is one of the most humanitarian acts that has ever been undertaken in peace time. The principle that someone shouldn’t profit from someone else’s ill health has been lost. If someone says an American health company will run the NHS efficiently, nobody can think of the principle to refute that. The guiding principles have been lost.” There was a study recently investigating why America, which spends more per capita on health, has worse outcomes, and the answer was quite clear: when there is a profit motive, the rich are overinvestigated, and the poor are undertreated. People die needlessly.

So there’s quite a sound pragmatic argument against private involvement in health, but Hall’s is a blistering moral statement – who would profit from someone’s ill health? What sort of person would that be? Would you trust them with your budget, let alone your health, or the health of a loved one? The moral case is not being forcefully enough put; indeed, it is not being put at all.
