"most people probably still have to wait in the US if you're lucky enough to get treatment"
This is really not the case. Over 92% of Americans have health coverage. I can also see practically any specialist next week....
How many choose to use it, though, and specifically, how many are afraid to use it because of cost? I'd count "waiting for an appointment/life to line up to see someone 'in network'" that as "lucky enough to get treatment"

It can be similarly the case in Canada if you pay out-of-pocket or with private insurance or travel, and people do the same in the US too.
