If one has insurance and/or sufficient financial resources, the question remains whether one has the medical expertise and equipment to carry out life-threatening treatment. Not all medical facilities are adequate, or they cannot be compared to what one knows in one's native country. Many responses indicate that, even among US citizens, people are forced to take out expensive insurance to receive medical treatment. However, realize that things can be different, and consider European countries where people pay a fraction. Of course, everyone has their own opinion, but it's only when they're confronted with it themselves that they reflect.
