If all National Insurance contributions went to the National Health and those that were not born here had to pay in for 2 years, before they were entitled to free treatment; then it probably would survive. However, not only does it have to contend with the natural population increase of the indigenous people of these Islands and the increase of those too young to work and those past retirement age; being supported by an ever decreasing number of workers ( proportionately )..........but it's also open to a free for all by anybody and everybody who wants to come here for treatment. So it needs to be sorted out, because the way it's going it won't survive.
