The difference is a cultural one. Americans don't complain when they see or experience injustice or poor behavior. Nobody will talk to a jerk like this in Europe.Or actually he will hear something. Like: "Can you take your shoes from the table Mr. Important? You are not at home! BTW, Jane did this work, not you, why are you claiming credit for her work?" I can't imagine someone telling something like this to a jerk in the US. At the same time I can't imagine someone not telling something like this to a jerk in Europe.
Also, never have seen so much politics and self-praise as in the US.
But then again, maybe a strict culture that puts everyone in their respective place, is the reason why we don't get Steve Jobs or Bill Gates success stories.
