There are some important factors people either forget or fail to realize which helps to explain why a Nation such as the USA could never have Universal Healthcare.
1.
Population Size
The USA Has a total Population of 329,000,0000+ which far exceeds the Population for any of the Average Nations within the
list of all Nations with Universal Healthcare.
2.
Quality of Care & Technology
The saying "You Get What You Pay For" very much applies to Health Care, contrary to popular belief; So much so in fact, that wealthier individuals in the very same nations listed, are known to partake in Medical Tourism to the US in order to take advantage of the higher Quality of Care. Suffice it to say, there is no way the USA could possibly afford to provide "Free" Healthcare at it's standard level for all 329,000,000+ Citizens (And counting, not even including Illegal Immigrants).

. Military
Here is a hard truth, a Nation ceases to exist without a Military & Strong Borders; this is actually a large part of the reason the Soviet Union could not possibly keep up with us and ultimately fell 30+ Years ago. Incidentally, A lot of the nations on that list receive foreign aid from us, often in the form of Military aid, which allows them to divert the funds that would ordinarily go to their own Military towards programs like Universal Healthcare. There is simply no parallel where Nations contribute more than what we have provided them with, much less to the level sufficient enough to cover our entire Military's expenses (Which is necessarily is the largest in the world because of our significance as a Superpower Nation & to protect the Sheer Population & landmass size, etc). I would absolutely love to see the shit show that would ensue if America finally pulled foreign aid from these Nations, watch their attitude towards Socialism change overnight or continue down their path of self destruction & Get Swallowed up by a larger Nation (Probably Russia or China).
I could go on, but I think I covered the biggest points of contention regarding this issue & Hopefully I will have inspired at least one reader to be more critical instead of just accepting common Narratives.
