The Short Version
This claim is the opposite of what the evidence shows. Multiple high-authority sources—including the Peterson-KFF Health System Tracker, KFF, and America's Health Rankings—consistently demonstrate that countries with universal healthcare outperform the U.S. on life expectancy (by 4+ years), infant mortality, maternal mortality, and avoidable deaths. The U.S. spends far more per capita than any peer nation yet ranks last or near-last on most key health outcome measures. Avoidable deaths are rising in the U.S. while falling in universal-care nations.
