The main reason for this is that the United States cannot afford to continue paying escalating medical costs. Therefore, political and social changes will have to happen to bring costs down.
Medicinal and technological changes will continue to push costs up. More drugs and more technology will always cost more money. But the US government cannot afford to keep spending more and more on Medicare. And both private and public sectors cannot afford to keep paying more and more for health insurance. Therefore, there will have to be political and/or social changes to reduce the amount of health care we consume and/or the costs of that care.
