The quality of US healthcare is better for the average person and the waiting lists are much lower or do not exist. Many from my country will travel to the US for healthcare and paid. So many advancements only become available 10 years later. Free health is never unlimited you always have to make tradeoffs.
I'd much rather be in the EU making EU wages than in the US making US wages. Europeans working in the US may not be in the same risk category as US Citizens (in the US) as they can always move back to EU if they face a health crisis.
