Hmm. Even though health care is a topic that's very close to me heart, it's sort of hard for me to form a valid opinion without having all the facts straight (stupidly, I've never done any real research on the subject, though I plan to change that very soon). Try not to take me too seriously.
No, we don't have universal health care in the U.S. and it can get ridiculously expensive at times. The thought of living without insurance (which is pricey enough as it is) is terrifying, because hospital visits, doctor appointments, medicine, physical therapy aren't cheap and can add up FAST. I know several elderly people who are in and out of the hospital all the time, having operations and getting therapy for just the normal conditions that come with aging- they can't be helped. They're all covered, I think, but to think that everybody their age can afford insurance is crazy. And it makes me extremely sad. (Oh, and dental work is also expensive. I'm not sure if that's covered by your Universal Health Care, but it can get sky high over here.)
And then the state of the medical facilities themselves really depresses me. Doctors are expensive, but people can't live without them. I know the overhead that comes with the practice must be high, but it's hard to imagine that they'd need that much money to do the more simple procedures. Every little thing just seems so darn expensive- heck, the rates per night to stay in a hospital alone are through the roof. I heard that it can cost THOUSANDS of dollars per night to stay in one.

Not to mention that nurses, especially for nursing homes, are desperately needed and there aren't nearly enough to go around. The ones that
are in the field are often inexperienced and/or just planning on staying in the job for a short while. But really, I'm sure that
all healthcare workers are overworked. Having so many patients to take care of and all that paperwork to sort out are enough to drive anyone insane, and they do the best they can, but it's gotta be hard.
So, even though that's hardly a thorough breakdown of our health care system (it didn't even scratch the surface by a long shot), I'm pretty unhappy with the way our health care works. If you can afford to pay through the nose for either it or some insurance, it's more or less decent (provided the hospital or doctor's office you have doesn't completely suck). But if not, then you're good and screwed.
You should probably ask someone who's better informed than I am.
