One effect of Obamacare and the growing number of doctors who will not see Medicare patients is that many of those patients might well begin seeking care in hospital emergency rooms.
Another effect is that patients won't be seeing doctors. They'll be seeing nurse practitioners, physician assistants and any other cost-effective paraprofessional that can be dreamed up. And if there is something that there is just not substitute for (neurosurgeon for example) these specialists will be threatened with criminal charges if they don't do as they are told, and work for whatever they are given.
It is to the point now that someone with a REAL emergency may die in the emergency waiting room before they get any care.
