I'm surprised no-one's used the following logical argument yet in favour of the NHS, or any large-scale public service. There was a tendency in the 70s towards inefficiency, but nowadays a single, modern health service could in theory aim to operate more cheaply through economies of scale and zero profit motive compared with a fragmented, privatized health market composed of competing, profit-driven companies. I'm not saying the NHS is an efficient, well-oiled machine running close to peak efficiency, but at least that is something the people running it can aspire to and seek to achieve, unlike those in the private healthcare market model, for whom profit is as much a consideration as patient wellbeing.
