Lol The US hardly has private healthcare. It's the most regulated industry second only to the financial industry. And the government uses it's control of currency and healthcare spending to dictate a lot of things we do in healthcare (I work in healthcare). We have to do all sorts of goofy shit because of government. On top of that, competition is stifled by things like Certificate of Need laws that prevent competitors from coming into a given region. This leads to very few providers being able to essentially do whatever they want. And insurance (financial industry, the most regulated) is pretty well controlled by government to the point that we can't really innovate there either.

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?
