I'm Canadian living in the US (married an American), and I would take Canada's health care system any day over the system here. The only "edge" the US has that I've seemed to notice in my time here, is that the clinics/offices are much more aesthetically-pleasing and expensive-looking... not really a requirement for quality health care.
I have Type 1 Diabetes and it's insane here in the US. $275/insulin vial vs $30 (of course, I can only get it partially covered if I buy 3 vials at a time now which is way out of reach and my deductible hasn't been reached yet, but paying 20% on $600+ is still a lot for me and that's only for one of the insulins I take). People, mostly Americans, are swapping their diabetes supplies -including expired ones, on Facebook groups just for the price of shipping because cost is so out of hand here. I am insured through my employer and the coverage is meh and I work for a large, international corporation. My coverage at a much smaller employer in Canada was better. I am currently using recently expired rapid-acting insulin that I originally received in Canada in 2015. I am going home for Christmas and will be purchasing insulin in my hometown in Canada. My visit at an endocrinology clinic with a NP was around $300 here in Southern US. My visit with an endocrinologist (the best one I've had!) in Quebec was free and they ordered more comprehensive lab work. Sure, that waiting room/hospital was fugly and the waiting room was very full, but my care was perfect.
My husband is currently uninsured and at home with a possible inguinal hernia. He's in a lot of pain, but has been refusing for days to go to the ER because of the cost and what a gigantic medical bill would do to us. I'm not a nurse yet - I'm doing prereqs, so I am currently the only one employed grossing a bit under $25k/year (my husband lost his job after STD wasn't approved for his depression because he didn't have a "history" with the doc who filled out the paperwork.. He had no doc prior! and I paid with my HSA for his appointment with my family doctor, but all proper care for his mental health problems have been out of reach). You don't know how much I wish he was in Canada right now just to at least have his abdominal pain attended to. No wait in the US (which I think is largely inaccurate) means nothing when you feel like the price of care is too much of a barrier to even get to the ER in the first place. Plus, in Canada I didn't have to wait and wait and wait in emerg when I presented with high glucose (not in DKA) and suspected I had diabetes. My care was very "wham bam thank you ma'am." But that's the difference between something that can become a real emergency quickly (ending up in DKA) and someone showing up with a headache...
I like lots about the US and where I live, but this ain't it.
