Blegh. Problem is, that government has been perpetrator of some of the greatest evils of our time. Soviet Russia, WWII, all problems cause be people becoming too dependent on the government, or looking to it to solve their problems. The problems caused by big business over the past 200 years have amounted to minor problems in the long run.
If we start offering healthcare to everyone for free, then that makes people that much more dependent on government. It erodes from there. People start looking to government to solve all their problems, and suddenly, fascism, totalitarianism and all their variants begin to pop up.
Government, while it may not seem like it, is a much more uncontrollable and dangerous force than any conceivable private endeavor. That's why libertarianism is useful.
The report's title you gave on taiwan up there, turns out it was asking was healthcare "Affordable". I did some of my own research, and it turns out that Taiwan is having it's own considerable share of problems, especially dealing with distribution of health care practicioners. Canada is having problems paying for medical treatment for extreme situations, such as cancer, that an insurance company would have no problems paying for. They're having to rely on public donations in some cases because the system just can't pay. The answer is always MORE FUNDING. Canada's GNP is already 11% health-related, compared with 9% for america (OK, fine, The U.S. Foreign fags). This comes about because when the cost to acquire a service is zero, then the demand skyrockets. I don't buy the whole "Catching problems early causes the amount of medical services that must be rendered to go down" shit that many socialized medicine advocates claim. It's full of problems, just like the U.S. Capitalistic system we have. Only difference is, I don't have to pay.
I also did some research on privitization of power grids ETC... and it turns out that while it hands services to individuals, it is not a true free market. It's is a complex managed system with so many points of failure, it's surprising the thing hasn't collapsed. They have bidding wars, where the one who supplies power at a lower cost gets to sell, which is OK in theory, but it's still a government mandated ogliarchy, full of regulation and price controls ETC... In a natural monopoly (only way for it to not be would be to have multiple sets of powerlines strung to every house, and while it's possible, I don't want that many telephone poles in my yard), so I don't really have an answer with regards to the free market system for you there. I only know that deregulation has worked for the most part, without any "significant increases or decreses in overall quality of service," To quote the article on Taiwan's healthcare system that you showed me.
I think you blow the problems of the US out of proportion while ignoring many of the problems of the countries you seem to have a boner for.
