A cautionary tale
One point I've made is that nationalized health systems can be cheaper because they deny access to their system of "universal" care. Here is one such tale.
I do find it absurd that the advocates of state-run care argue that it will provide "universal" care when it does no such thing. As far as I know every single nationalized health system rations care. What they mean by "universal" care is that everyone gets some care just not all the care they need. But that is also the case in the United States under the current, screwed-up, mixed system of care.
