Do Europeans sometimes look down upon certain types of Americans?

Part of me regrets moving to Florida from New York. Yes, the weather here is perfect, and there are a lot of economic opportunities for those few people willing to get a good education and work, but there are way too many people who are like my neighbors, whom I share a driveway with.

This morning, they were out there, getting Earl Junior ready for school (it's his second go-round in second grade), revving up their giant truck (that requires a ladder for L'il Earl to climb into), talking really loudly and blocking the driveway. Big Earl and his fat wife were wearing matching NASCAR jackets -- you know, with all the labels on them. The color theme was mostly yellow with a big Cheerios logo written across their chests.

So I look out of the kitchen window and Krystka, my European girlfriend, is waiting impatiently on her moped to get by this hulking mass of metal and car exhaust and rednecks. She beeps the little horn on the cute orange moped, but they can't hear it over their engine.

Finally, she gets off the bike and yells in her cute Polish accent, "Can you move that environmental nightmare, you freakin' hillbillies?!"

They didn't take too kindly to this, telling her to go back to her own country and to hug a tree. I believe they also called her "Eurotrash." I ran out and made peace (I never talk to these people), and they went about their business. I find such longtime locals easy to manage, but Krystka, on the other hand, had a difficult time with them. I have heard her making fun of less educationally advantaged white Americans before, come to think of it. For example, she told my daughter once that a boy who was interested in her in school, the son of a single mom who works part-time as a lunch aide, would someday be "pumping gas" and to aim higher. Another time, Krystka said that she refuses to shop in Walmart because "the dregs of humanity shop there, drinking beer in the parking lot and belching."
