Most Americans would probably agree (the cost of) health care for all Americans is a major issue for New Democrats of the 21st Century. Most would probably also agree we'll eventually arrive at some solution intended to provide health and dental care to those who don't have it.
The debates of the past explored grandiose schemes of all descriptions, but failed to find any that didn't lead to ultimate bankruptcy for the nation. The reason was that everyone, the medical professions, the pharmaceutical companies, the insurance companies all had to be somehow compensated for the money they'd lose.
However, one approach to national health care everyone's carefully avoided mentioning, but which is already in place and working is the US Public Health Service. Expanding an existing operation should prove to be a lot cheaper and easier than beginning from scratch, re-inventing the wheel.
Every Native American with a tribal census number is provided complete free health care, hospital care, prescription drugs and dental care, cradle to grave. The US Public Health Service has been quietly performing this function for a century and more at a cost that's evidently modest enough cost to avoid raising eyebrows.
To set a National Health Care program into place all that's needed is an end-run around the big-money physicians, pharmaceutical companies, dentists and insurance companies. All the endless debates can be avoided while setting the inexorable forces in motion that will end with defacto National Health Care Program.
Create more Native Americans.
Issue a tribal census number to every person born within the boundaries of the United States.
All the ancillary issues of funding will inevitably follow.
