If you pass triage, and wait your turn... And outside of hospital emergency visits, if you can find a family physician. Free has a large time cost associated with it.
I'm in Norway (immigrant). I've had no issues finding a family doctor. Other immigrants have had no issues at the hospital emergency room (I've not personally needed it). They even send me reminders to get cervical cancer screenings once every 3 years. Sometimes the appointments aren't as fast as some people would like, but I ran into similar issues in the states with some doctors and most definitely with specialists. And most times, it has been tolerable. When I've really needed in, my family doctor worked me in to see her.
The cost isn't that large. Especially not compared to what I got in the states: Folks spending 2,000+ on maintenance medications for different diseases. Going without care for things. And so on. These aren't exaggerations - these were myself, friends, family, and pharmacy customers.
Perfect here? Nope. But I'll take it.
