This “list” thing is not what I’ve heard about from relatives who live in “socialist” countries; though it’s been a few years since discussing it with them. Maybe it’s changed in the past few years. If it’s not imperative to get treatment right away, you might have to wait a bit, but if it’s an emergency, they are treated in the same manner/timeframe as patients treated here. Of course, there are variations between countries.
In the U.S., the hospitals are only obligated to treat people (for free) in the ER if it’s a life-or-death situation, or if they are seriously injured or sick; they only have to “stabilize” them. Trying to get follow-up care is the tricky part, and if an expensive procedure or treatment is needed, good luck with that.
Nonetheless, your friend’s input is very much appreciated. Enjoy your visit!
