    197 – Healthcare spending – mo' money mo' problems

    13/08/2026 | 42 mins.
    The United States outspends every other country on Earth on healthcare but shockingly does not have the best outcomes and ranks 32nd in terms of life expectancy. Switzerland spends less and does better. Plucky little Canada ranks 22nd in the world. Kim Moon is back to explain why more spending doesn't equal better outcomes and what really drives higher health care costs. Also, a comparative analysis of the US and Canadian healthcare systems: what works and what doesn't in each country.
