How Much Would Universal Healthcare Cost if America did have UHC?

So yeah, basically my title, How much would we be spending? More or less? According to to studies by the Congressional Budget Office, the General Accounting Office (GAO), the Lewin Group, and the Boston University School of Public Health. The GAO estimates if the United States changed to a universal single-payer system, it would save in the short run: $34 billion in insurance overhead and $33 billion in hospital and physician administrative costs.  


I also like this Myth and Fact from amsa.org (which stands for American Medical Student Association )


MYTH: The United States has the best health care in the world.


FACT: The United States has higher infant mortality, higher surgical mortality and lower life expectancy than Canada. The United States has a much lower rate of access to primary care doctors than Canada. Canada has the same acute care bed-to-population ratio as the United States. Patient satisfaction, quality of care and outcome of care in Canada equal or exceed that in the United States, according to the U.S. General Accounting Office. For this lower quality, Americans pay 40 percent per capita more than Canadians do on health care.
