Cultural analfabetism?

How can people in the street somewhere in the United States of America be so totally blank on trivial jeopardy questions about world geography, history , religion, warfare, past and highly actual events. OK - these may be the worst examples, and you could probably find ignorants everywhere. Or, is this an example of complete cultural blindness, US centric unawareness of the Outer World? Mention a country that begins with a U? Utopia!

An eye opening video.
