In reply to summo:
You're conflating the proposed Social Care changes with the above idea of funding the NHS through the deceased person's estate.
Clearly the NHS has to be funded by either general taxation or something more targeted. However, funding the NHS from dead people's estates will mean people putting a price on end of life care. It will mean asking people to put a price on their life at the time of their most vulnerable.
Lets put it another way. The QALY mechanism for rating the value of new drugs rates a year of life as worth, roughly £25,000. So, if a new treatment can give you five years of life, the NHS can spend £125,000 on it. Ten years and we can spend £250,000. Many cancer treatments are at or around this cost threshold. How many parents need to be put in the position of choosing between their quality of life and their children's before this mechanism becomes morally dubious?
That's not to say I extend those opinions to Social Care - I don't know enough about the concrete proposal in the Tory manifesto to have an opinion.
There is a relatively straightforward solution in the long term to dealing with this in the NHS: statistical modelling, risk stratification and a greater targeting of services to those in their 30s / 40s when we can change the patterns of behaviour that make people more likely to become chronically ill in their 60s and above. This works; the problem is that it won't deliver for two decades. Therefore, it's not popular politically as it won't deliver in the 5 year cycle that govt cares about, politicians worry about policies that exclude people (if someone is targeted someone else misses out) and you have to work out how to bridge the gap.
I think, in the medium term we're likely to see greater devolution of health to local authorities and LAs merging with CCGs. What makes you and keeps you healthy is mostly out of the NHS's hands; it's your community, education, the quality of your housing, job opportunities, public transport, etc. Having one healthcare organisation - in an area - that deals with the needs of the local population holistically makes sense. The 'danger' is that as services merge, there will be a clash of Social Care and healthcare ethos: the former is means tested, the latter is not. At some point, that gap is going to have to be bridged.
