Just imagine you know nothing about the US except what you see in movies. Do you see a lot of poor people?
There obviously are movies and TV which show a much more "real" version of the world. But the most popular TV and movies tend to show an idealized version of reality.
I can't imagine that because I was raised here, that's why I'm asking. I saw plenty of poor people in real life and in popular movies; when I see American movies, it looks like home to me, it's where I grew up.
