Why Are Some Countries Rich And Others Poor?

Why are some nations rich and others poor? In a new book called Why Nations Fail, a pair of economists argue that a lot comes down to politics.

To research the book, the authors scoured the world for populations and geographic areas that are identical in all respects save one: they’re on different sides of a border.

The two Koreas are an extreme example. But you can see the same thing on the border of the US and Mexico, Haiti and the Dominican Republic, and dozens of other neighboring countries. In all of these cases, the people and land were fairly similar, but the border changed everything.
