A nearly universal consensus has developed in the United States that the current health care financing system is a failure. The system has been unable to control the continuing rapid rise in health care costs (by far, the highest in the world), and it has been unable to stem the growing population that has no health insurance coverage (at least 36 million people). There is nearly universal political agreement that government must provide health insurance to a far greater share of the population than ever before. The political debate now focuses on whether this expanded government role should supplement the private insurance system with an enlarged public program covering those left out of private insurance coverage, or replace private insurance with a universal government health insurance program covering the entire population.
