No other wealthy nation even has this debate.
Plenty of other wealthy countries don't have single payer health care.
Japan, Norway, Finland, New Zealand, Italy, Portugal, Sweden, Finland, Spain, most Gulf countries. Some people call Portugal a multi-payer which is disputed because SNS is free, universal, national, etc. Even the countries which have Multi-payer or Mandates like Germany etc have 80-85-90% of the system as Single Payer within the Multi-payer/Mandate system. Multi-payer potentially could be a better option but ACA was the multi-payer/Insurance Mandate type option & it failed.
It is impossible to implement unless both parties are ideologically similar - So that they don't play around with coverage or income levels. Plus, in US multi-payer/Mandate type universal healthcare is impossible considering the courts will find an income level & forced insurance like Germany unconstitutional !
Finland has a public option.

https://en.wikipedia.org/wiki/Single-payer_healthcare. Canada and Taiwan are the only ones with single-payers. Others have multi-payer. A 2001 article in the public health journal Health Affairs studied fifty years of American public opinion of various health care plans and concluded that, while there appears to be general support of a "national health care plan," poll respondents "remain satisfied with their current medical arrangements, do not trust the federal government to do what is right, and do not favor a single-payer type of national health plan."[106
