Greed is not a "culture".
And I say, money? How ironic as money (as in coinage) is heavily ifluenced by Greek culture.
Fight everyone attitude was embraced by England (Britain), just read the history books.
You constitution and laws are based on "English Common" law, all of which is an evolution of the Magna Carta (again in England).
So again, what has American culture done for me? Hollywood? Oprah? TV? Movies? (All would have been better answers than the one you gave).
Not really... Greed is a very integral part of the US culture.
At least I think so... The excess, the desire for more... that was embedded from the time the Bill of Rights was written... Rights to own things... Be happy... on and on.
Again, I'm quite certain if you look at the amount of money that US spends purchasing your exports, you will find it to be a big portion of your GDP.
You can say it doesn't influence your culture, but I would say it does.
As far as TV and movies.. or Oprah?
I don't find any form of pop culture or entertainment "influential"... If you do, that's fine by me though.
I find money much more influential on all cultures than TV.
Question, would you find things like Coca-Cola an influence on culture? What about baseball?
