Taiwan

Although Professor Hsiao says they adopted a system similar to Canada's single payer system in Taiwan, it is easy to recognize aspects similar to other countries. Taiwan allows its citizens to choose their providers similar to Germany and the UK. It is comprehensive like the UK and Canada, it covers herbal practitioners and acupuncturists like many other Asian nations, and it also covers dental, vision, long term care, and in home nursing. There are co-pays to pretend the longevity of the system, unlike the UK. This system is really good and their are positive results to prove it.
On behalf of the US, I would most likely adopt the universal mandate from Netherlands. The risk pool idea of having everyone insured or if not insured still contributing to the pool really makes sense.
