Not far from here is a place called Shriners. They treat burn victims (mostly children) for free. What I hope this says is that the private sector and private donors can and are, willing not to let someone's body lie broken in the gutter.

Yes, we do, however our government has stepped into the act of providing for others while the private sector is being nudged out. I would agree with much that you've attributed to us as a people, yet our charity and compassion in a private sense have been replaced by government mandates that limit our ability to perform as we might in the absence of government controls. Let's not even discuss government efficiency in delivering services.
