The US economy thanks you for getting out of the way, I guess. Americans aren't flying to Europe for healthcare - it's the other way around (if you can afford it). So it may be "superior" in the sense that you're just paying for it your entire life via taxes instead of at the time of service and through employer-subsidized insurance, but it's not "superior" in terms of care.
Politics shouldn't be anyone "vs" anyone else. It should be "how can we fix what's broken, how can we make what's good even better." Trump's message was largely "here's how I will fix the economy" and "here's how I will fix the border." Harris's message was "I'm not Trump" and "I won't change any policy of the Biden administration."
She left the group on the way back so she could stop elsewhere and get her teeth cleaned. She said it was a common sentiment for Americans to cross the border for dental work like that.
(That trip was odd for many other reasons ...)
