Nice read.
I pretty much thought of all those points already before reading it, except for number 4.) I'm not certain if this applies only to Americans and certain people have found them to be a bit more open than this, though who knows...maybe so. Maybe us foreigners haven't met many 'average' Americans and only the moreso exemplary individuals that either greet us or come over to visit us. *shrug*
That said, some of these can easily be applied to other countries too, so again Americans...don't feel too special. There are plenty of other countries that share these kinds of cultural baggages as well. But yeah, ultimately this combination is moreso specific to you and yes - it does point towards a very consumer-oriented culture centered around comfort rather than happiness I suppose.
That said, I think point 2.) is definitely something most Americans would do well to remember. To demonstrate with an example, for which I am very certain I will get flamed for even after a decade has passed, not 3 months after 9/11 in our country there came out a funny song about a faux-arab accented guy singing "I love my papa and I love my mama, but most of all I love Osama." and about how at least he sees his house on CNN now that the towers went down and the Americans decided to go into Afghanistan.
Understand...this song wasn't written because the songwriters hated America's guts, nor was it written because they genuinely loved Osama. And no, it wasn't a viceversa feeling of emotions either! It was just simple arithmetic of what makes something humorous. Namely: Distance + willingness to find humor in even a morbid event. That is all. It was no more 'wrong' than Americans making fun of say...Canada for its infamous hockey hooligan riots, that result in actual looting, destruction and even death.
But the reason why these things, such as our song, are considered funny over here is not because our country collectively hates America. As the article author points out very astutely - we're too busy with our lives to hate a country we barely think of. It was because we were observing the fall of the towers from a distance. The same as you observed the Canadian hockey riots from across the border.
It's just the way the world works. Every culture makes light of each other, but doesn't really hate one another unless something like a war breaks out between them. And indeed, America is no exception to this rule. You're just another country to the rest of the world. And no matter how much you might try to upgrade yourself from that status through rationalizations made to others and to yourself, it will never change.
And that's not such a bad thing. Because it can form the basis of seeing how other people in other cultures deal with the same problems you face in your everyday lives. Stuff like your job, relationships, getting to do something new every once in a while,...you know...life.
