Well, I won't wax political here, but economic: nations with national health care systems (that is, those financed by government, which means taxes) all, to some degree, must ration delivery of said health care. In Canada and Britain, rationing is usually done by waiting lists and limited access to some high-cost procedures. It appears that the down-under countries are applying some immigration limits as well, to prevent some people who may want to come in from doing so if they are seen as being high-level consumers of health care services. Simple economics shows us why rationing of health care services will always be a feature of nationalized systems, since in those countries they are funded by a finite tax base that also has other competitors for available dollars (education, defense, social welfare, etc.) If you doubt this, ask yourself, all things being equal, where would I rather have surgery, my local community hospital or the VA or one of those large inner city public hospitals? (yes I know you can get quality care at those places too, but be honest -- most folks rightly see government-run hospitals as second rate, for good reason . . . )
