For an average person, Italy, Spain and the UK have better healthcare systems than the US by most metrics. The US is only better for some very obscure and exotic diseases that require expensive and rare treatments that most US citizens wouldn’t be able to afford or wouldn’t be covered for under their health care plans.
I’ve all kinds of not nice things to say about the US healthcare system but their ability to not get overwhelmed during this pandemic compared to Italy, Spain and UK is remarkable, as the parent poster (probably unintentionally) mentioned.
