Do you believe there are leading elements in countries? I don't think Rick is trying to say "every" person from the United States, or the country by itself must be/represents -valuing. I think what he was getting at is that there is a pretty high likelihood of people being so, or at least the way the society portrays and is built upon can be seen that way. For example, simplifying the US from popular culture: Rags to riches, American Dream, Rosa Parks, Space Race, Capitalism, IMO sounds like + .
I don't intend this thread to be a history lesson as it can severely get off topic, and I know there a billion of factors that come into play; culture, state, city, neighborhood, people, parents, upbringing, the fat kid who says "O'Doyle Rules!" but if I were to rephrase the question:
If countries were IM(s) what do you think they would be?
