How to ration?
Oh, everyone else does not get care - my family does.
Or, “friends” of the party in charge get care - others do not.

Well at least the political class, which exempted themselves from this obomination, will get taxpayer paid health care. You, probably not unless you are in your prime 18 to 45.
