You know, I'd be interested in hearing the details of how all this works in countries like Canada, Britain, or say Sweden. Not a comparison mind you, but the nuts and bolts of going from being in the health service to going to see your doctor.
In Canada it may differ from province to province.
Here in Ontario you simple go to your doctor or walk-in clinic or hospital and present your Health Card. This is an ID that allows you use of the system. Once there, you're registered with them for future visits. The ID is photo for most these days, but for old farts like me, it is not a photo one. Every time I see the family doctor, he sends in a bill to the OHIP for his payment. Same with specialist that are covered.
Eye and dental are not part of OHIP, though with eyes, as a diabetic, I can get OHIP coverage. Anything else requires either a separate insurance plan or cash. I've paid cash for dental. For prescriptions, that's your own plan unless you can get on some government program for help. But those can be total bullshit and result in no help.
Basically, in all our taxes is blended in the health funding, in both federal and provincial. It's been there since prior to my entering the work force, so I don't feel it any different then any other tax.
I really don't see why it cannot be set up similar to us down there. Federal tax for federal level plan, then a State tax for the more specific plan for that state. Issue a card or two, one fed and the other state, and off you go. The money pools for all and as long as hospitals, doctors and such do not over charge and of course are watched for that, there should be no problems. That and making sure folks do not abuse the emergency rooms.
