Very cool link! This is one of the questions I love to ask first-time visitors, since they have been subjected to USA tv, movies, music,etc. for all their lives,what most surprised, or amused, or startled them, and I also say that nothing they say could offend me, I really want to know. Some of the answers I have gotten:
Every child in a family have their own bedroom, even if all are boys or girls.
How big houses are, even for the middle class.
The "compact" cars here are bigger and more powerful than most European "average" cars.
How much the CEO of a company makes compared to the regular worker, and even more than the President.
Restaurant portions, and the obesity they see regularly.
How America does not take universal healthcare and really quality education and good public transportation as the right of every citizen, and to pay taxes willingly to support these public good.
How until 9/11, America lived in a bubble like nothing bad could ever happen here, and how shocked we all were that it did.
Really makes one think, doesn't it?
