U.S. compared to other Developed Countries

So for this blog I am not posting more statistics about public opinion but rather talking a little about the research paper that I have to do regarding health care. Last semester I took a politics class titled Public Policy, and it compared United States public policy to other developed countries. One of the things that struck me as the most interesting was the comparison of our health care system to the other developed countries especially Europe. The United States is the only developed country that does not have universal health care, which I find to be really interesting. One of the main things for the research paper that I am going to be looking at is the public opinion of the United States and other countries when it comes to health care. Do people in countries that have universal health care have a positive opinion of it? What do they think about the United States not having universal health? Should the government be responsible for health care? These are all questions that I am very interested in finding out. I am still unsure on what my direct opinion on the matter is, because although I have reasons for wanting the government responsible for health care (kidney condition, and a sister with MS), I have also heard about the problems that come with universal health care. An example of a problem that I personally have seen with universal health care happened to my cousin who lives in England. My godfather Jimmy has been in kidney failure for over a year and was put on the waiting list for a kidney transplant. Waiting on the list for a kidney can take over 5 years so it is best to try and find a match in your family. His sister Janice, who lives in England, was a match and was willing to give him her kidney. Because England has universal health care the process of Janice being tested (there are lots and lots of steps that have to happen before you donate) took a very very long time that would have happened a lot faster if she was in America. So it is clear to me through this scenario and what I learned in my Public Policy class that both America's health care system as well as universal health care have its problems, and I am interested in learning more about which system has more benefits then flaws. Let me know what your opinions are on this. What do you think about America being the only developed country without universal health care?
Hope everyone had a good weekend.
