I have analyzed these myths below. In each case my answer follows a brief summary of the original point.
1. Multiculturalism: No one else is close in the ethnic variability of the US. It affects our decisions to work together in ways not even fathomable elsewhere.
I live in a neighborhood where practically everyone is an immigrant. They're all different ethnicities, from all over the world, but they have one thing in common: They're all poor. So you're saying that our country is great because people come here from all over the world to clean hotel rooms and serve hamburgers.
2. Social mobility: you still can go from outhouse to penthouse.
The US does not offer its people the best chance of becoming well-off. Many other countries give their poor people a better chance to get rich. ln the US, only 6% of people born into the lowest economic group (bottom one fifth) make it into the top economic group (top one fifth). see Economic Mobility of Families Across Generations for details. Countries with a better chance for improving your status are Denmark, Norway, Finland, Canada. see Page on brookings.edu for details.
I love the part where you say that immigrants take advantage of educational and entrepreneurial opportunities. The educational system is rigged so that very few people get elite educations, and most of those come from privileged families. The cost of a higher education has become so high that many poor families can only afford to send one child to college.
The US has some laws that favor entrepreneurs but many others that do the exact opposite. For example, becoming a doctor is a way to get rich, but states control the number of students who enter medical school and the number of doctors who can practice medicine. They have strict laws forbidding non-doctors from practicing medicine. Once again, these laws harm the very poor, who cannot afford a real doctor and instead use faith healers and patent medicines.
Every entrepreneur knows that what you earn depends on how much you have to invest, and poor folk got nada.
3. No cost lawsuits: Other countries haver loser pays for court costs.
It used to be easier to sue a doctor in the United States, but Health Insurance companies and vulnerable corporations--like those that sell tobacco and asbestos--have made it much more difficult to sue anyone. An individual rarely can afford to do so. Many states have passed "tort reform" laws that limit the amount you can receive and also prevent class action suits from being filed. A recent $5 billion class action judgment against big tobacco companies was rejected by an appeals court that said class actions can't be joined by people in other states. So every person injured by tobacco-related diseases must join in a lawsuit with others from their own state. Since these cases last for years, it may not be possible for people in small states to recover their losses at all.
Tobacco companies and Asbestos companies have learned how to game the system so they pay only pennies on the dollar for actual costs of deaths due to their life-threatening products. Asbestos companies did this by declaring bankruptcy, then allotting a small amount for future damage claims. Afterwards, they can start up business again without worrying about the consequences of their former actions. That outcome results from the lenient bankruptcy laws of the US.
Besides, if everyone has health insurance, the costs of health care are much lower and there is no necessity to sue. The US has the highest health care costs in the world but its high costs do not make their people healthier.
4. Americans view of the value of life: We put those over 70 on dialysis, ventilators and other extraordinary measures.
The belief that Americans place a higher value on life than elsewhere is a myth. Americans have an average life expectancy of 79.8, while Sweden, Iceland, Norway, Finland, and Italy all have higher life expectancies. These are all socialist countries that have national health systems. If they placed a lower value on life, they would let their people die. But they keep them alive longer than the US does.
5. A fundamental difference in how we are constructed: It is ACCESS TO not the NATURE OF our health care system that drops the US in all the rankings.
I don't understand how you can separate the nature of the health care system from how many people it refuses to care for. You're saying that our health care statistics are worse because we don't provide health care to the poor. You just complained because other countries ration health care by age (which isn't true), but you're saying the US system only looks bad because it rations health care by wealth.
Yes, the US looks bad because poor people can't afford necessary health care. Many lose their lives needlessly because of this system of rationing. This results in a health care that looks bad and is bad, unless you judge a health care system by the way it treats the rich. If those statistics where the US looks bad only considered the health of the rich, the health system would look better. But then you couldn't compare it to the other countries of the world, which do provide health care to the poor.
I suppose you're actually claiming that the US can't afford to give health care to the poor because there are so many poor people here. But the median income in the US is among the highest in the world. See Household income for details. So what you're saying just isn't true. The median family in the US has more money to spend on health care than nearly every other country in the world. The reason we don't provide health care to our citizens isn't because we can't afford it. It's because people like you believe that it is acceptable morally or philosophically to deny health care to people "from the third world country" inside the US.
6. Paying for everyone else's research: Our drugs are DRAMATICALLY more expensive.
Public Citizen has published an extensive report on the claim that drug companies need higher prices to conduct essential research. The report concludes, "But this R&D scare card is built on myths, falsehoods and misunderstandings, all of which are made possible by the drug industry’s staunch refusal to open its R&D records to congressional investigators or other independent auditors."
Every other country in the world pays less for the same drugs than the US, despite the fact that publicly funded scientists provide much of the research for these drugs. The drug companies have managed to convince our Congress that every other country in the world is wrong to pay less for drugs. They have done this by spending large sums of money on lobbying and public relations. The US is the only country in the world that falls for this stuff. I guess that is a form of "American exceptionalism", but I think it is something we would all be better off without.
