There's no point in explaining that. A lot of them have never been outside the country and maybe Canada. Even if they can afford to go somewhere they don't have the time. They can only imagine the world outside as a version of what they know. And everywhere they went hasn't been very different from what they have at home. They won't be able to imagine it.
Interesting. When I visited the US in 2003, I recall the news reporting on a study showing that more than half had never been to another country, and they stressed that that included Canada and Mexico.
It became a bit of a discussion point during the ride with the those I visited.
