My list:
1. American people are just people, like any other. Some are great, some are morons.
2. Their political system could use a redesign. Ya can't tell the Dems from the Reps. Both are in the pocket of the bankers and large corporations. They need to repress half the world to keep their military busy. They elect some scapegoat every four years so they have someone to burn in effigy everytime things don't go their way.
3. Their military may be one of the most technologically advanced, but they abuse that superiority and should have their pee pees whacked.
4. American industry has a "the world is our oyster" attitude, no matter who they have to screw over to get what they want, which is just about everything.
5. They have one of the highest crime rates because the country is run by criminals; an elite that thinks it lives outside the law. Lately they've been getting caught with their pants down (literally).
6. Their education system produces zombies for the factory, much like Canada, only worse.
That is it in a nut shell, and because they have 10 times more people, they have at least ten times more nut cases.
