AmericanSamoa is an 'unincorporated' territory of the United States, meaning the US Constitution and certain other laws don't apply.
American Samoans are US 'nationals' and have all the rights of other Americans except that they can't vote in presidential elections.
American consumerism is rife with big American SUVs and pickup trucks cruising slowly down the roads, stateside-style stores selling US and Chinese goods, and bulky residents munching salty or sweet fast food.
