We can't afford the NHS to which we've all come to expect as our birth-right.
I am thinking £5 a visit, not £50. There has been a strong correlation shown between people's respect for things they regards as 'free' and those they pay for. A charity worker once told of a village elder who told the charity to charge a small sum for schooling they were about to provide for free to MAKE people attach a value to it.
As for the cut-off, we constantly draw lines in the sand as to who can or can't access things. It's not hard or innovative to do so!
The 'bring back matron' idea is hackneyed- a great sound byte but coming from a very different era to the one we have now. Health care has changed beyond recognition. We'd be rioting on the streets at the death rates those 1950's dormitory wards with matron in charge 'enjoyed'. And can you imagine a modern patient falling subservient to Matron (images of Hattie Jacques!)? We 'expect' young nurses to do so but we sure as hell wouldn't ourselves! It apparently 'worked' as a system because EVERYONE was scared of Matron!
MRSA and C Diff aren't actually MADE in secret laboratories in hospitals, contrary to what the red tops would have you believe: Their prevalence has come about due to unimaginable old age being attained by the majority of patients these days; a plethora of modern drugs that have the side effect of weakening the immune system of a challenged patient yet further; the way we the public DEMAND antibiotics for every twinge then, because we're not THAT ill and 'don't like taking drugs', we take half the course; our belief that 'good medicine' is measured in minimal length of hospital stays.
The 1950s patient would, at 65, considered himself to have had 'a good innings' and be more sanguine about the reality of what was then considered to be 'old age', the illnesses and mortality.... whereas today I know of relatives who have come marching into hospital demanding recompense because 'Grandma came in here, fit and healthy and you killed her!'... OK she was 89, she HAD spent the last 9 years in a care home, she DID have an intractable chest infection and kidney failure, she WAS bed bound, but none the less! She was only 89!... seriously. With that anecdote, I touch on a well-spring of community attitude towards illness, wellness, the NHS. We cannot meet people's crazy expectations and if we want to improve, even save the NHS, we may have to be a bit more 'creative' in our health-care delivery.
Whilst this is all not entirely relevant to the OP (and yes I have actually read all 17 pages!) I think it has a bearing, and the message: Be careful what you wish for.
