No, America is generally a well liked country - both for vacations and sabbaticals, and for actually moving there. However, Norway is much more of a left wing country politically, so many of the base values are quite different.
There are also other cultural differences that mean some Americans can come off as a bit abrasive to us, though I think those are often the ones that come off as such even to other Americans. Flaunting your wealth or your privileges is mostly frowned upon in Scandinavian countries, and one's not supposed to think too highly of oneself.
PS: This particular sentence is from a song by David Bowie, where it is followed by the line "I'm afraid of the world", so it does not reflect on Norwegian sentiments about America(ns).
I'm a little confused about that ending--is there a rule about when one ought to drop the first 'e' in the definite plural '-ene' ending? That is to say, why would it not be 'amerikanerene'?
(I found a note in the Plurals section that dealt with words already ending in '-er', but I couldn't find anything in the Definite Plurals section about how to treat those words in the definite plural.)
