Both uphold principles of universality and equality by mandating individuals to purchase health insurance on the private market, providing financial assistance to those on low incomes, and regulating the insurance market in order to protect those with poor health (from your post about the Swiss and Dutch model)
Presumably medical and nursing staff are employed by the private companies, Whitewave?
Presumably there would have to be reductions in tax/NI to compensate individuals for having to pay premiums to the insurance company?
Where do aspects of public health like epidemiological surveys and research fit?
I'm a little sceptical about insurance companies I confess. They tend to put their own restrictions on things, like what treatment options they will pay for, and which practitioners patients can see.
