It is not a no-brainer at all because the Canadian system means garbage for all. I have seen my father treated here and in Florida and the difference is absolutely striking. Now, I know that you seem to disregard personal experience but, to me it counts and what I also hear from many others.
"Garbage for all" in the sense that it has the same outcomes as the US system, at lower costs. You are right that I give very little weight to anecdotes as opposed to scientific studies with data sets that can show significance.
That said, I think that Canada actually has the best of both worlds--everyone gets good healthcare at reasonable prices, and rich, grass-is-greener people can jump down to the USA. And Canada gets to be a freeloader on US medical R&D. It's actually awesome for the rest of the world that Americans are happy being grossly overcharged.
Two major reasons for that is abuse by patients with many still going to see their doctors for minor scratches, colds and
doing things that they could do on their own such as blood pressure.
This would actually be interesting to test, because preventative stuff is typically very cost-effective. So, it would be interesting to know if the preventative effect of people going to the doctor "too often" actually saves money.
Also, how much is spent each year on free and repeated STD's detection must be out of this world.
Not sure what your point is here. We shouldn't test for STDs? People who enjoy having sex are evil?
I actually was curious what the number was here, but couldn't find it in 5 minutes of searching. Thanks for ruining my browser history.

People paying a little bit for each visit would help a lot.
I'd be totally into trying a small fee for service (small relative to the patient's income), to see the impact on both costs and outcomes.
And extremely strong unions and terrible hospital administrations who render the system unproductive.
Don't forget doctors deliberately restricting the supply of physicians. It's amazing that with all these factors adding inefficiencies, the US system is over 50% less efficient, isn't it?
Then other stupidity from the system such as prescription renewals requiring a visit to the doctor and pharmacists who can't do basic/common sense prescriptions.
I agree. I bet this is another "doctor monopoly" thing.
So no Canada is not perfect. Very far from it.
Yeah, it certainly isn't perfect. It's just far closer to perfect than the American system.
