Hog,
To answer your question about teamwork.....
Everyone got into the "spirit" of being a patriot for a few weeks there. Everyone was waving flags, and patting cops on the back...making donations to firemen, etc..........but then it happened.....life went on.
Americans went back to worrying about themselves and only themselves. The race for the dollar came back and nobody cared anymore. Materialistic views and lifestyles, and the "I don't care, what can I do?" thought prevailed once again.
It's sad I suppose.
