Until you have paying customers, as in using the £100bn NHS funding as a health insurance, there will be no changes as all hospitals and staff get paid whether they are excellent, good, average, poor or awful anyway. We know from the soviet experience that command industries and monopolies of supply are expensive and don't deliver.
With my ex-wife I had to pay for her to go privately as either the waiting list was unacceptable or the treatment on offer and doctors attitude was not acceptable. So I ended up paying twice; taxes and private treatment.
Why do we allow Governments to set up monopolies of supply when they are quite rightly illegal in the private sector?
If you want to know why many rich people live to a very old age it is because they can afford immediate and effective treatment when they become ill (The same applies to the royal family). The private hospitals only earn their money from giving treatment, not saving money by starving and dehydrating them to death.
