Saying "oh that's just first come first serve" is totally missing the fact that the service level can be woefully inadequate.
What's really crazy is that I live in a small city of about 100k people and there are about a dozen hospitals that I can choose from, first-class trauma centers, multiple renowned research centers (affiliated with three different universities). None of that is counting all of the urgent care and other facilities in the area. I have an order of magnitude more options for treatment than I did when living in New York City...
The only way I could open myself up to more/better care options would be to move to Texas.
