I suspect that many of the people in these oppressed countries have the idea that the U.S. is like Disneyland–everything’s free and there’s plenty of everything.
Have you ever seen a movie (animated, Don Bluth) called An American Tail? It’s about a family of mice who immigrate to America. Before they get here, they sing a song that goes, “And there are no cats in America, and the streets are made of cheese.” Great song, and I think it captures the mindset of many who immigrate (legally and illegally) to the U.S.
It’s a good move, and the most famous song from it is the beautiful “Somewhere Out There.” I highly recommend it for children, but be careful–there ARE cats in the movie and they want to eat those mice!
