I agree with the sentiment of that post. The only thing that I'd add to that though is that when it comes to trauma care, I can't think of anywhere else I'd rather be than in a big city here in the US. I believe our country's trauma care is probably the best, if not among the best in the world.
Otherwise, yeah, greed/power/control and ego are elements that prevent us from being the best.
