I am 68-years old.  I use my private group health insurance to provide for my needed health care.  Although I paid into Medicare for much of my adult life, it does not provide for ambulatory care nor medicines.  The polices that are available to provide such coverage cost more than my current plan and have deductibles, which mine does not.  I would oppose putting the rest of the country on a system that has to be subsidized by private coverage after all is said and done.  Even if you changed the system to provide needed care, the administrative cost per patient to provide Medicare is $509.  The cost to provide coverage under private plans is $453 per person.  Where are the savings?  After 35-years in health care management and public affairs, 30-with the Federal government, I know that most people are doing their best, in public and private systems.  Why turn an entire industry on its head for philosophical reasons?  Universal access to care is possible with a public/private system.
