The USA is the only major country in the world (and in the history of the world) that is not forcing its model on anyone else. The moment one lands in any country of the world, one feels the pressure to become "one of them". It has been that way for thousands of years. On the other hand, the moment someone from Tanzania or France or Guyana enters the USA doesn't feel any pressure. That person keeps wearing the same clothes, shopping at the hours s/he prefers, eating what s/he likes, worshipping the god sh/e prefers and listening to the music s/he likes. Anywhere else in the world this is difficult, if not impossible, if not illegal. (A few exceptions, but they are very small countries). Anywhere else in the world there is a model (cultural, lifestyle, economic, etc). But an "American" model does not exist. The USA is a country of immigrants, and wildly heterogeneous immigrants. There have been countless empires built by immigrants/invaders, but never one that was built by a number of culturally/linguistically/etc different immigrants/invaders. Furthermore, this is an ongoing process, that may never end. The USA is a mixture of races, religions, ideologies, etc that evolves according to a Darwinian process. If enough people like a feature (whether pizza, reggae or Buddhism), it will survive and reproduce. Even the economy changes daily. It is not true that the USA is a capitalistic country. That is a gross simplification: each start-up is almost a communist state; many companies are run by the employees; and almost each major company works in a different manner than the other ones. Again, it is a Darwinian system. There is no official set of "American" features. Almost every decade of the USA, in fact, has had different features. The thing that we call "the American system" changes almost daily.
