I just ran into this story this morning. It's only five people, and I think the story is slanted in favor of single payer. The couple of points that were of interest to me across the five countries were:
1) They all seem to kind of say the same thing - they like it and you can see a doctor right away, well, except for if you have an illness (preventative medicine rules) and then you may have to wait a couple of months for an MRI or whatever. I'd actually prefer to wait a couple of months for preventative medicine appointments. Having a need for an MRI or other advanced mechanism means there's a chance you have something more serious. I'm not keen on hearing, "Oh, sorry Ben. If you'd only gotten in a couple of months earlier, we might have been able to treat the cancer."
2) Even the interviewees with advanced education pull the, "It's free because the government pays for it" routine. No, you pay with your taxes, so you pay for it. To tie it in to point one, they seem to be okay waiting months for certain procedures because "it's free, so that's still a good deal". If they realized it was a service they paid for that they are not getting in a reasonable time, maybe they wouldn't be so happy with the bad service. But then it has been around so long in some of these countries that if you're born into it, you just don't see a problem. Kinda like with gun rights, where some people born into GCA 1968 don't really gripe about what was lost because they never lost it. it's just always been that way for them.
