Communism takes control of a society in little tiny bites. Each one so small it hardly seems noticeable. An unfunded mandate like this is just a strange and twisted tax on a very small slice of one industry. Hardly enough to piss any significant group of people off, but certainly enough to destroy dozens of fine hospitals, manned by fine and courageous Americans.
I would suggest the owners of these hospitals simply close their doors. That is the only way to get any attention on the problem. So long as they continue to scrape together enough resources to keep their doors open, the congress will think it has done a good thing.
