Nobody on this thread has pointed out that people are already "paying" more than just tax as a result of the poor state of the health service. For example:
The loss of income caused by needing to take occasional days off work - either for one's own health condition or that of relatives, children, neighbours etc. - is also a form of "payment."
For some people, the almost total loss of income - i.e. they have had to give up work or reduce their hours while waiting for their condition to be treated, or while caring for someone else who is waiting;
The costs involved (time, petrol, parking, lost earnings etc.) in travelling to a hospital 30-40 miles away for an appointment because the local hospital doesn't have that specialisation or doesn't have a certain item of equipment;
The emotional cost of being unable to see a GP, of waiting months to see a Consultant and even longer to actually be treated and not knowing with certainty when the situation might improve (while the health condition continues to deteriorate). The emotional cost of having long-awaited surgery cancelled at the last minute. The emotional cost of the loss of independence - of being reliant on others for transport, shopping, social interaction, or for essentials such as hygiene, food and getting around the house.
None of these ever enter the government's calculations - they only count the direct costs to the Treasury and ignore the losses or costs to the individual. Which is a false way of calculating, because if a person can no longer work they become a "cost" to the Treasury (in the form of benefits payments and support etc.) and an additional "cost" in the form of lost income tax revenue, and lost VAT and other revenues as the individual earns and spends less.
