What is your evidence for this? The US is almost alone amongst developed countries in not having a government-run general heal care system, and has the highest costs (while not covering everyone).

And Medicaid, Medicare, and the Veterans Administration (the three big government run healthcare systems here) all run more efficiently by every measure than any private health insurance system.

Note that I fully recognize the problems that the VA has had, but when you really look at it fairly, they have many parallels to problems in the commercial side of the system, we just don't tolerate that when it comes to government (nor should we).
