Sometimes, an outsider can see things that locals take for granted
Living in one place for all your life tends to give a provincial view of your world. If all one has to go by are articles and TV programs, then you can't begin to know what another country is like. Quick, tell me about America, but first, have you spent any time here? If all your opinions are from the news or popular entertainment or even a brief visit, then it's pretty safe to say you don't know squat.
