Anecdotes aren't evidence, but . . .
My family carries a trait which sometimes causes minor problems. It's no big deal (well, the Air Farce docs finally wigged to it and kicked me out, but that's another story).
It can also cause a far worse problem, as I learned one night when I had some really strange symptoms. Nothing major, just several parts of my body going haywire at once. I had to go to the ER to pick up a friend, and since they weren't busy, I decided to get checked out. About an hour later, I was in an MRI to confirm the doc's diagnosis. They transported me to a larger hospital with the proper specialists. They did another MRI.
Less than six hours after I checked into the ER, I was being prepped for open-heart surgery at a world-class hospital.
My condition was one of those things you never really hear about, and then when it happens to you, everybody knows someone in the family who had it.
I found out two of my distant relatives here in the states had the same thing, with similar results. Everything turned out well for everyone.
A relative in Canada (socialized medicine) died in a waiting room. He'd been there more than eight hours (his symptoms weren't considered serious enough to warrant being treated quickly).
Three relatives in England (socialized medicine) had the same condition. One died before he could get in to see his doctor. One died during the week between seeing his doctor and getting an MRI. And one lived! About six months, then died of endocarditis (a really, really nasty way to go) because the doc took a quick look at him, said he just had a cold, and sent him home without a proper exam.
So let's tally that up -- three of us here (including me with crappy insurance and one without any insurance at all) got proper treatment quickly and lived, while four (living under the wonderful umbrella of socialized medicine) all died because of lousy access to doctors and crappy treatment.
I'll just leave this one little thought for you: when have you ever known of any government program working efficiently or providing great service at a reasonable cost to the taxpayer?
