Incorrect. In the U.S. a child can be forced to receive medical care against the wishes of the parents, and a child can be “protected” from medical treatment that is deemed unethical.
While Charlie Gard may have been permitted in the U.S. to receive the medical treatments his parents sought, it would have nothing to do with who got the bill and everything to do with such treatments being considered ethical for a child in Charlie’s condition. Even so there are still limits to what can be done as a medical treatment, especially to a child, in the U.S.
You are talking about an entirely different matter than what occured with Charlie Gard.
