That's not true in my experience - it seemed like Americans seek less care, because it was expensive; but when they do, they seem to want to medicate everything away and go back to work ASAP (even if it's something that heals on its own, and even if it means taking painkillers for a while and risking complications), whereas in other places, it is acceptable to let many things run their course, and mild discomfort is considered acceptable.

E.g., in the netherlands (and IIRC also in Germany), it is considered rude to come to work when you are sick - you expose everyone else to risk, for a work day that's likely less-than-effective (because, you are sick) -- whereas in the US, you're expected to just pop an advil and show up (and .. if you are visibly suffering, you'd be considered a hero).
