Ok. So the original purpose of the NHS was to apply a few bandages and treat TB ..... and a few other things. No cancer surgery, no hole in the heart surgery, almost no antibiotics, no blood pressure treatment, no effective mental health treatment etc etc etc. Medical knowledge has changed and hence costs are higher. To base what you treat on what was envisioned in 1948 makes little sense.
Why is renal failure/tranplant, heart failure/transplant .. a choice? Similarly Obesity, alcoholism, drug addiction are not choices, they are all illnesses. I agree, society can choose not to pay for their treatment, but blaming patients for choosing to have those illnesses makes no sense. The Commonwealth study referred to above is very clear that the NHS is excellent value, we are not paying any where near as much as the French, Germans or Americans for health .... and on that basis I would argue we should fund the NHS more generously.
