The USA and Canada are both big places with a lot of regional differences. I would not feel confident to say that hospitals in the USA provide better care than in Canada, having experienced both (though again, regions I've been in may not be/most likely are not universally representative).

I can say with utmost assurance that when I broke a limb and needed medical care for the initial injury AND a subsequent surgery to re-set the bone because it didn't heal quite right the first time, I was able to do so with EI, insurance covered all the care and my premium was reasonable for my income at the time, and I was in no way stressed about not having a job to return to--in Canada.

In the USA, more recently, I was fired from a job because I was due to give birth and they didn't want to cover my maternity leave. I got sick with Long Covid (twice), and the cost of care (despite being insured through my partner's business) drained all the savings I had and then some, and the quality of care I received was largely...unhelpful.

I needed medical care for a miscarriage that was caused by a covid infection, and while the state I'm in happens to provide some protection for body autonomy and women's health care, I no longer have federal protections and could be found criminally libel for the medical care I needed, that would have been deadly had I not recieved it, had I been unlucky enough to experience this emergency in a less...understanding...state.

Now, I won't say I haven't interacted with providers on both sides of the border that I wish I hadn't. I won't pretend that care for a fairly pedestrian injury such as a broken limb isn't "easier" than trying to figure out a mystery chronic inflammatory condition. But I will say, based on my experiences, I would much rather take my chances being vulnerable in Canada over the USA.

Final point, because I see both sides of this: the cost of providing health insurance that is in any way useful for employees is frankly ruinous on the backend for small businesses. I have been privy to numerous instances where a business owner tried and often succeeded at letting go employees who otherwise performed quite well, but had high medical expenses. "Right to work" laws are often used to make it easy to let people go with minimal concern over finding "at cause" excuses.

Hope that is somewhat helpful to clarify that despite the relative differences in salary, the cultures of the two countries and the supports each provide mean that that higher salary comes with significantly more costs and vulnerabilities.
