Even in Canada you can pay more to get better or faster care. You'll always have overpriced options that by definition won't be worth it for people who can wait, and you can shop around the world if it's not an super emergency and you're really willing to spend.

If that doesn't resonate, it's the same as schooling: you can have good and cheap public schools accessible to everyone, and private schools that will cost 5~20x more but provide a significantly different education.
