Any alternative funding system does not conjure up more young people wanting to go into healthcare... unless we all pay more for free tuition/parking and higher salaries, let alone more equipment, scanners and hospitals...
Then there is all that additional bureaucracy to be paid for.... millions of claims to be picked over.... co payments and treatment excesses to be accounted for... Directors of Health insurance companies to be paid ... and of course the "performance bonuses" they'll need to attract the "best people" to run these Not for profit organisations......
The truth is that the UK chose lower taxes and hence less public spending, which is why all our public services are so poor.
An insurance based health system just means higher taxes, dressed up as insurance premiums.
Why not just increase taxes and ring fence into the NHS ? bring our health spend per capita up that in France Germany....
