Are Americans Really Know-it-alls?

A comment on a post: "I don't understand, but then again you americans think you know everything!" from a Canadian. It was a little misplaced, because I was almost in a state of wonderment that possibly the Canadian government administered their farm program(s) entirely through the Internet. Obviously I wasn't clear, but the commenter makes a very serious charge.

Of course, I often claim to know it all, that's an occupational hazard for a blogger. But do Americans think we know it all? Really? Remember Rex Harrison in My Fair Lady: "men are ...." ("A Hymn to Him) Just replace "men" with "americans" and that's probably fair, "we are a marvellous sex..", we only want others to be like us.

I have to plead guilty to the charge on behalf on 300 million + residents of the U.S. At this point, it's appropriate to refer to the post just below this one.
