I think it is a culture based on greed and materialistic consiousness. We are unique (mabe, because I haven't been in any other cultures) because we seem to be able to advertise more than is ever necessary.
We also seem to think that we can all be special, even though there has to be unspecial people for the outstanding ones to stand out. We also seem to like to buy a whole lot more than we need, rather than focusing on the things that make us happy.
If something happens to us, then we feel all hurt and hate anyone who isn't sympethetic. If something happens somewhere else, then we have to stick our hands in whether or not we are making the situation better or worse.
We probably have the highest percentage of people who think that this country is the best thing ever, even if those people have never left the country, read about another culture, or even thought about our country at all. These people (of any country) are the bane of the world and should all be shot.
Furthermore, I don't think that we have any other countries' culture in ours, because we are intolerant of all other cultures. See the above paragraph for the reason why.
The only places that have other cultures are kept to small areas that are concentrated in large cities. Any other small towns, villiges, ect. are sanitized against any other cultural influence by close-minded fools.
So in closing, no. We don't really have any other culture's (to my knowledge) influence felt here. We are the unique assholes of the world.
