Well regulated doesn't mean public. It's the owner that counts...
So as i understand you are in USA and you work in healthcare. Tell us more please of how the system works or should work. For example i heard a story with one person having an accident and a finger cut. In the hospital they needed a significant amount of money, 5000$ or so to fix it. That person didn't have the money so they didn't fix it. They assured me that such barbaric stories are true in USA. Is it?
