I know what you mean. Fortunately the ERs here aren't shutting down but they are being affected. I just paid a hospital bill and it was about $300 more than the last delivery (just a few years ago) which had more complications. I talked to the accounting dept. They said all was in order. I asked if I could be bold enough to ask them if the increased cost was due to and increase in cost of the uninsured, specifically illegal immigrants. The accountant openly said yes (I got the impression they weren't too happy about it either).
They weren't sure about the ER's operations as they didn't oversee their budget/billing but believe they are still running in the black. One can only hope.
Try skipping out on an ER bill as a citizen with a permanent address. They'll threaten to sue. The corrupting influence of all this fraud is going to end up eating away at the honest behavior of everyday people, who would never have even thought about being less than aboveboard, before all this. It's pernicious.
