So what is it about universal health care that has everyone on red alert?

I hear people telling tall tales about how horrible Canada's system is. Just because Obama has a universal health care plan, that doesn't mean it's exactly like Canada's. France, Japan, Norway, Sweden, Denmark, and the Netherlands all have really good health care systems. Almost every other developed nation has universal health care, and it's working in those countries. Since when does the Constitution say, "All rich men are created equally?" When more than 50 million Americans are uninsured, that's a crime against humanity. When obesity is overtaking this country at the same rate greed from the insurance companies are, there is something wrong with this picture. When more than half of the nation is overweight, and something small like the swine flu makes everyone jumpy, imagine what will happen when everyone starts getting diabetes and has no health insurance. Would you all rather sit back and watch the insurance companies milk people for every penny? So what if doctors will make $500,000 a year rather than $750,000. Their standard of living will still be better than that of 95 percent of the entire country. People should really go into medicine because they want to help others and not for the money. We have to try an unusual method about health care now because the usual method obviously isn't working. So I will ask you all again. What is it about universal health care that has everyone with their panties caught in a bind when it's worked just fine in all the other developed nations?
