Some countries have long had welfare systems that operate like insurance and there are probably advantages in it. The cost becomes more visible to everybody. People can see at a glance how much of their taxation is going to the maintenance of health services.
The public would probably take a heightened interest in hospital costs, general practice subsidies, disability support services and sickness benefits. Health has been the hardest item of public expenditure for governments to control. Its costs keep escalating far in excess of annual inflation and practitioners meet little taxpayer opposition when they press for more.
The accident compensation scheme is a much more transparent fund and the corporation is more capable of limiting its liabilities, checking the claims made upon it and ensuring that people on compensation go back to work as quickly as possible.
The corporation would be no less rigorous if it was paying out for illness. The sickness benefit, which seems to have become the default category of social welfare in recent years, would be replaced with earnings-related compensation and recipients would be regularly assessed for a return to work.
New Zealand's no-fault scheme for personal injury insurance remains a rarity in the world. The Woodhouse commission was originally asked to consider only workplace accidents, that were previously privately insured. It took it upon itself to recommend a scheme for all injuries, paid from taxation and vehicle registration as well as employers.
A further step, to insure against incapacity of any kind, is probably too large to contemplate. But its possibilities for controlling public health and welfare costs should never be ruled out.
