The U.S. health care economy represents 17% of total GDP, up from 15% in 2010, and tripled since 1960 (5%). In real GDP it eats up more than $3 Trillion dollars per annum. The U.S. health care economy is a top-10 world economy by itself. To quote Warren Buffet "There's only so much of the pie it can eat." We're simply being eaten alive by the U.S. Healthcare system.  

There's zero downward economic pressure to reduce costs. Moreover, the U.S. medical model is solely procedure based and not an outcome or preventive medicine based model.  The bonuses are the fact that the leading cause of death for people under age 50 is death from opiod overdoses, physicians prescribe 80% of the world's painkillers to 4.6% of the world's population, and the life expectancies started their unabated downward arc. Throw in the fact 100,000 Americans, on average, die from hospital infections, preventable infections, mistakes, malpractice, etc. So we pay more to simply die more. Insurers win in the end.
