You know what citizens won’t have to pay for outside of their taxes? Premiums. You know what citizens won’t have to choose? Food over medication, medication over housing, going bankrupt over lifesaving HC or choose between HC and education.
Yes, it’s not a perfect system but it is far better than what the US has today or any other time in its history.
