I see that we've got into the "we can have the NHS as publicly funded free at point of use" vs "we'll be like America" discussion.
There are better ways as pp have said:
The health care system in France and Germany is a mixture of state and private funding. Everybody has insurance according to their income.
I think the biggest problem the NHS may have (I haven't researched but I'm sure other posters are better informed) is that the funding isn't ring-fenced for the NHS and all taxation goes into a pot and the government of the day prioritises. Therefore yes, under Labour who are traditionally seen as underfunding the military we ended up buying our own boots and body armour. And under the Tories who really would rather have an at-least-partly privatised NHS the spending is different.
In Germany the money that is paid for the health insurance goes directly to the insurer you picked. You can select whichever one you think suits you. Mine pais all my medical costs and included, free of charge, my two DCs until they reached the stage where they got their own (student, apprentice).
Where i think the NHS should improve is in 2 areas. 1 is the way it is used and the services it offers. Hard as it will be for some things they will have to be rationed - and that will probably include things like viagra, IVF and other non-life-threatening procedures. (I'm not talking about stopping, I'm talking about rationing). And not in a means-tested way because everyone contributes to the NHS
and 2nd I think they have to look at their management / procurement structure. People always go on about how the NHS has too many non-medical managers, but they need people who know how to work properly in procurement, preferably with extra training for the NHS. And their sourcing needs to be widened (including qualifying suppliers, other industries manage it, there is no reason the NHS couldn't)
Some fault lies with the users. you only have to see some of the discussions after a "AIBU to have gone to A&E with my ingrowing toenail" type threads to see what those faults are.
Interesting comment about how the charitable donations are used, though, loved the description of the alzheimer's patients and their bus stops.
