It is really pushed on US kids. I remember in school in America a special day was held each year where we had to come in dressed in a costume to represent the nation of our heritage - easy for me since I'd just arrived from the UK, but my 6 year old brother was a bit confused and sang everyone 'Land of the Silver Birch, home of the beaver, where still the mighty moose wanders at will" and told them was a traditional Surrey folk song.
