I have been reading Why Nations Fail by Daron Acemoglu and James Robinson. The central premise of the book is that political institutions are the primary determinant of whether a nation will be prosperous or poor. Anyway, I came across a picture in the book of North & South Korea at night which helps demonstrate the sharp contrast between the two countries. I had seen such pictures before but thought it was interesting enough to make it into a post.
