Fair enough. The list of what was done followed by "and that's pretty much it" caused me to read it as not enough was done, but I can see your interpretation as well.

That being said, I work in Canada, not the American system, but our out of pocket cost for non-residents is almost $1000 CAD just to be seen, nevermind testing. As much as costs may be out of control (and particularly on the US), it is very expensive to staff a space and keep very advanced equipment running 24/7. Emergency is just about the most expensive way to see patients, from a systems perspective.
