My notion of "public healthcare" is being able to walk into a government clinic or hospital and get free treatment or appointments as long as you show you're a citizen -- sorry for not having cleared that up.

I personally do like the single-payer approach, where you get coverage on a no-fee basis purely by showing you're a citizen/resident; and that's how it's done here in Denmark. But it's not the only way of providing universal care, even in Europe. Germany, Switzerland, and the Netherlands are typically considered to also have universal healthcare, but it's administered via health insurance, not as a single-payer model with direct state provision of services. There are various options for coverage, but having some baseline coverage is mandatory and intended to be universal (with subsidies for people who can't afford it), somewhat closer to the ACA model than to the Scandinavian or Canadian model.

Except you said the U.S. doesn't have any public healthcare.

I changed my original comment to "public universal healthcare". I once again apologize for the lack of clarity of the original comment, and I hope you understand what my point was.

Europeans visiting the states are genuinely worried that they will be carjacked, which I always find hilarious. Life is not like the movies or the news.

It is unsettling the number of Americans I meet that seem to have the same worries in their own country. The level of fear and paranoia is great.

Americans don't worry about car jackings because they don't have a cartoon view of the US.
