The concept of a NHS is wonderful and years ago it was amazing. I now think it has gone completely to pot. I would feel very scared having an NHS operation, for fear of contracting one of the superbugs.
The NHS does need to stay, as there are many people who could never afford private healthcare. Maybe a new scheme should be introduced, where those wishing to go private, should have their National Insurance contributions put into a private healthcare scheme and the patient would then pay the balance themselves.
Also, people who do not pay taxes or National Insurance or who do not have permanant residency to this country, should not be allowed to use the service free of charge. If you go to any other country in Europe, then free healthcare for non residents is not available
