Originally the NHS was to keep seriously ill and injured people alive and fit enough to work.
Then the demands became greater - it was expanded to be available for less serious ailments which would previously have been addressed at home, but which were better treated professionally.
Then it moved on to not just providing appropriate treatment/surgery, but also providing a good cosmetic result - so surgery didn't have to just be effective, the scar had to be tiny and neat etc etc etc
Then it was expected to be there for "vanity" operations - breast enlargements etc (yes - for some people this was important for mental health, but plenty demanded them for bigger, better whatever that they wanted but wouldn't or couldn't pay for themselves) - and added to this became the repairs for surgery that many people had done abroad privately because it was cheaper, but which ended up being botched.
And all the way through this were increasing numbers of "health tourists" who deliberately travelled to the UK for free treatment - theoretically this money can be recouped from many governments; in practical terms it rarely is - as well as advances in medical science which mean that the service supplies more and more procedures, requiring more and more expensive equipment and drugs, and more specialist and highly skilled staff.
And the patients now demand private rooms, televisions, a choice of menu, unlimited visiting hours which make actual nursing more difficult.
And procurement of even "minor" things (like soap) is locked into particular suppliers - there seems to be no transparency about how contracts are awarded - who charge premium rates for what they supply.
There are ever more tiers of management; which may or may not be necessary - I don't know, but when cuts are made they always seem to be among the frontline workers - management seems protected.
And of course, there are people who aren't happy (like Branson) with some aspect suing the NHS and taking money out. How did he even succeed in that suit? Had he been the victim of a medical error which affected his life - fair enough - but all it was was that he didn't get a contract he wanted. So what? Isn't that what bidding for a contract is about? You might get it, you might not?
I think the NHS is amazing, and it should continue - but it needs a re-think as it is attempting to do things it wasn't designed for.
