For a few Americans. Not for all Americans, and probably not even for most Americans. There's far more to the United States than New England and Southern California.
Don't get me wrong, if I had some rare cancer or other strange disease, chances are I'll want to try and get in to one of these few rare ultra premium hospitals. But if I break my leg or get some normal infection or have a child or any of the other normal kinds of issues people have? Will that still be the best tier of care?
