The cynical view is... Selfishness and egocentrism play well with consumptionism. I think it starts with natural isolation and weak societal bonds in the US (haha, as far as it can be observed in Hollywood movies). People lack something then and they are offered a lot of entertainment. That entertainment is more often than not something you buy. And then at some point the US corporates realized the US market is not so big. Or it is big, but the total world is bigger. And they can or even need to export their goods and services. And when exporting they often need to sell and market their products using feelings. These feelings are often pictured in American context, even if the content is presented abroad. TLDR: I think it's intentional.
