I don't know if it's easier to propagate stereotypes today (if you study history you'll realize that stereotypes aren't hard to propagate or spread, even with minimal media - a voice is generally enough) but this story was told to me sometime during travels in Morocco and I sometimes think of it when the term "immigrant" is tossed around as if it always meant the same and as if everyone who leaves a place for another place means to stay there forever. A part of me is nomadic, so this perspective comes more easily.
