I keep seeing people say that Medicare in its current form is not sustainable, as if that were an established fact. It’s anything but.
What is Medicare? It’s single-payer coverage for the elderly. Other countries have single-payer systems that are much cheaper than ours — and also much cheaper than private insurance in America. So there’s nothing about the form that makes Medicare unsustainable, unless you think that health care itself is unsustainable.
What is true is that the U.S. Medicare is expensive compared with, say, Canadian Medicare (yes, that’s what they call their system) or the French health care system (which is complicated, but largely single-payer in its essentials); that’s because Medicare American-style is very open-ended, reluctant to say no to paying for medically dubious procedures, and also fails to make use of its pricing power over drugs and other items.
So Medicare will have to start saying no; it will have to provide incentives to move away from fee for service, and so on and so forth. But such changes would not mean a fundamental change in the way Medicare works.
