1. Can You Guess the World's Fastest Growing Economy? (No, It's Not China)

Mongolia is part of a new class of countries that, like the Middle Eastern states that got rich selling oil to the West, have hitched their economies to resource-hungry China.

5. The Rich Have Feelings, Too

 At the risk of sounding condescending, we should point out that ordinary people haven’t the faintest conception of the strain we had to endure daily.
