Are you assuming that Medicare gets no additional funding? My assumption is that every dollar which currently goes to insurance companies as premium ends up going to Medicare[0]. Medicaid would have no reason to exist any more either, it would become part of the same program. The only way this ends up being more expensive than what we have now is if we must cover a bunch of people who are currently doing without health care.

That would be offset by all the money we don't spend on medical billing and insurance company bureaucracy. [0] or whatever it would be called, Medicare is a nice name but I'm talking single payer
