It is not the culture, it is the legislation. Based on a bit of a research USA is the only country that has a Constitution that grants real rights, like freedom of speech, religion, etc. while in the others there are almost zero rights by Constitution, they are privileges that can be suspended or retired. For example, UK or Australia don't have a freedom of speech as such; in Australia the Supreme Court "interpreted" in a decision that freedom of speech is a right, but not because it is in their books, just because they gave that interpretation. Such ruling can be changed later like it sometimes happen. For example in Romania, where the number of cases and deaths per million is low, there is no right; by Constitutional text there is a freedom of speech that cannot be infringed, but in practice we have laws that infringe it and they were not considered non-compliant with the Constitution. For example, anyone saying there was no Holocaust will go to prison, even if that is an opinion protected by the free speech article. All other articles have a formulation "in the limit of the law", that means any law can limit any right. At the same time, one of the first measures of the Government when the lockdown was instituted was to announce the European Court for Human Rights that Romania is suspending human rights. Plain and simple, we have no rights, stuff that can be changed, suspended or taken are not rights, but privileges. Including the right to live, patients with chronically diseases were restricted to get medical care during the lockdown. Therefore comparing USA with the rest of the "Western world" (Europe and eventually Australia, it is not about geography but culture) needs to take in consideration the situation of fundamental rights in the legislation: USA has fundamental rights, nobody else does.
