Your reasoning is absurd based on the evidence.
The U.S. Spends more than 17 percent of its GDP on health care, the next nearest country spends 12 percent, or 40 percent more.
We have higher infant mortality and shorter life span than almost all other developed countries, and we leave 50 million uninsured. Even at its best, the Affordable Care Act will still leave about 25 million uninsured.
In the U.S. Medicare Advantage insurance costs 13 percent more than equivalent Medicare coverage and administrative costs for Advantage plans average 11 percent compared to Medicare's two percent administrative costs.
The evidence is in, government run health care is more efficient than the privately run systems in the U.S. I have yet to find a counter example. The evidence speaks for itself.
Our current health care system is a giant subsidy that cost Americans more than $750 billion per year. (Five percent GDP, which is about $15 trillion for the U.S.)
Sometimes, government regulation is needed and necessary. We are still suffering the subprime mortgage crisis caused by a lack of government regulation. A single-payer system would cost less and cover everybody.
