In the US, when I need a doctor, I get to see one right away. If the doctor recommends an MRI or ultrasound, I get it right away. No six month waits, no cancelled surgeries, no doctor strikes (!), no government deciding how to prioritize my medical needs, etc.
What it ultimately comes down to is that medical resources are scarce (and always will be while medical technology is improving and thus some care is expensive), and having the government allocate them can be inefficient (governments are generally inefficient due to lack of competition, as are systems where the customer is disconnected from the cost).
And yes, I care more about my own health care and that of my kids than I do about the health care of some stranger thousands of miles away. I have okay corporate health insurance and so the system works better for me than for some. (Some would argue that regulation rather than economic freedom are to blame for those people's worse experiences, but I'm not going to get into that other than to acknowledge it.)
You might disagree with some of my perspective, but the snooty attitude that Americans are oblivious morons is unwarranted.
