Well, if you cut out 35% of the cost of healthcare for shuffling paper bills by the insurance companies, that reduces the cost of health care to us, immediately.
Then you cut out all the money we spend on health care, the cost of Obama care, the cost of Medicaid, the cost of Medicare, the cost of CHIP...children's insurance, the cost of the VA healthcare, the cost of Tricare for Military retirees, the cost of healthcare for the Military at home spent, the cost we pay for health care clinics that we put up for the poor, the cost of what we give/pay hospitals for the uninsured poor, etc etc etc and then add in the amount of money employers are paying now to insure their employees, and some of what we spend right now for our own health care insurance....
And add all those things we spend on health care already, plus the savings from not having all these insurance companies to shuffle paper....
we probably could have a 'medicare for all' type system....
