Call for the creation of a universal single-payer health care system in the United States like Canada's Medicare or the United Kingdom's National Health Service. All medically-necessary medical care decided between physician and patient would be paid for automatically and directly by the Government of the United States, ending the need for private insurance for such care, recasting private insurance for supplemental care like dentistry services.
The national system would be paid for through taxes, replacing insurance premiums. Eliminating health insurance company profits and their administrative overhead would reduce health care costs enough to cover the uninsured and everyone else with ease.
An additional benefit would be the financial relief for businesses and employees.
