Care to elaborate?

Presumably the complaint is the article is shamelessly pandering to twenty-something college educated people who are already aware of America's shortcomings.

The article isn't at all meant to persuade anybody, it exists to pat people on the back who already believe those "10 Things Most American's Don't know". But not the reader obviously. The reader is too cool, it's those other Americans who are uninformed and stupid, you see.
