Horrible idea...
The purpose of an emergency room is an actual emergency... Immediate pain or immediate threat to life/health. If a non critical person can wait at home, then the wait will get worse for those who need it for an actual emergency. The non critical person should NOT be trying to enter an emergency room, they should be trying to get an urgent appointment with a doctor or they should go to an urgent care clinic. This is one of the many reasons Obamacare is a very good thing. If everyone is covered, people will no longer need to clog up the efficiency of an emergency room if all they need are antibiotics or something simple and non emergency. This is a very bad idea, Obamacare is a very good idea.
