Canada, the United Kingdom, France, Italy and Japan don’t use healthcare insurance companies (HICs) to ration healthcare. They can afford to cover everyone with the savings from eliminating the following:
HIC sales forces, admin, advertising, profit and outrageous CEO bonuses
A very expensive amount of paperwork and rules to comply with from the menagerie of HICs. Hospitals and doctors pay for this and pass it on to us through our health insurance premiums, deductibles and copays. This is the worst part as single payer systems have only one set of rules and forms.
