Clearly every single american isnt subject to the same cultural pre-occupations, that's absurd.
But there are only certain cultural phenomena possible in one place or another. A right-wing party in the UK could not even begin to use any of the ideas or rhetoric of the republican party - they'd be widespread revulsion. We dont sing our national anthem in the UK, we dont "pleg" anything, we dont consider our country "Exceptional" (hence American Exceptionalism). There hasnt been the suggestion that our prime minister is impotent for not interfering in Ukraine, at least, nothing like the inferiority-complex about Obama's lack of big-dickery.
The idea that the west is culturally homogenous is "Bullshit". As compared to anywhere in europe, americans are vastly more market-oriented, mistrustful of government, approving of business success, etc.
It is simply the case, insofar as I can see, that "business" isnt really a dream of any kind in europe. People dont grow up wanting to run/own/be in business in anyway, we dont really have an "explorer"/inventor dreams either.
A considerable amount has been written by the european experience of america and an almost ubquitious theme in the accounts is "the feeling of unlimited possibility", an ostentatiousness and pre-occupation with wealth, etc.
