Life expectancy vs healthcare spending of rich OECD countries. See chart source. The US wastes so much money due to useless middlemen (health insurance companies), and people not going in early for health problems. In Canada most healthcare is paid by taxes, and so overall there are no bills, no medical debt, and no medical bankruptcies overall in the main Canadian single-payer healthcare system. So people overall go in earlier for help, before conditions get worse, and before help gets more costly. Canadian healthcare has problems, but nothing like in the US.
