I would really like to see public health exclude obese people. It should already be happening, but isn't. It won't be a genuinely equitable system until these limitations are in place.
A doctor not performing an operation because the patient is not medically fit enough for it has nothing to do with any issues of rationing. That could happen to any patient of any age under any health plan, not just medicare.
Do you want your government making that decision based on arbitrary scoring protocols, derived by bureaucrats, or do you want your doctor and you deciding, after consultation, with you weighing the risks and benefits and you ultimately deciding what risk you'd be willing to assume. If it's a choice between certain death and an 80% chance of life, and for the record 20% mortality is considered high risk, would you like to choose or would you prefer bureaucrats choosing for you? And yes, patients have the ability to decide on receiving the high risk procedures today, and those procedures are reimbursed by medicare. You can bet your life, they will be denied in the future
We already have Medicare. The only question is whether everyone can have access. What do you think is going to change - and why?
