1) The condition itself is curable or treatable
2) The illness is teratogenic or a life injury or infection, and cannot be passed onto children
3) Children can in principle be had, ie the patient is of breeding age
Society has an interest and benefits from covering and expediting the cure fully.

In all other cases, private healthcare and insurance is the only option, and where that fails and the person is suffering too much, charity is the option. I believe we are a charitable people, and without nonwhite leeches on the system, charity can handle a LOT.

(Its also in the interest of the nation to fund preventative measures, and research new cures and treatments, but thats not healthcare per se)
