Public Insurance Vs Private Insurance

What is the main problem with the option of government public health insurance?

How exactly this will pose problems for private insurers when used in conjunction? Example: FedEx / UPS / United States Postal Service. Other than adding large deficit, I do not see why everyone is so worried about the issue. Enlighten me. So there will be an unfair advantage because the government can lower costs forcing significantly increased competition on private companies, but at the same time, lowering the quality of the offer at a price so low? bump to the question additional details added.

The right fear it will bite into the money they receive from insurance companies. I am always amazed that many Americans seem unaware about the real health issues relying instead on FOX and other sources to spread lies about the system of healthcare in the United States and those abroad. I mean, if care health in countries with universal coverage is so bad, why do they keep? Obama wants to make insurance more accessible to all and change the system so it gives the American people value for money [1]. It will also change so that the insurance companies more difficult to evade payment for treatment. The system he proposes is similar to working in Taiwan, where private companies are involved in providing Health [2]. Obama has campaigned on reforming the health system. He said he wanted to make insurance more accessible and it has been elected by the American people to [3]. FACT – the United States have higher rates of death for children both for children under one and those under five countries of Western Europe as the universal health coverage [4,5]. REALITY – Insurance companies are pushing U.S. prices and work to stop paying claims on those they cover [6]. FACT – the United States spends more on health care per capita than any other nation the world [7]. This means that an American died four years would have a better chance of living if they were born in any other Western country health coverage Universal. If you do not like the policies that Obama has been elected to, he can always be removed from office in 2012. But if you're disagreement with the facts, please let me know. I am always willing to learn, but please provide evidence. None of those who disagree with me have been able to do so far.
