This photo, if you haven’t seen it, is way cool. It’s the earth from space, at night. But for a real contrast, look at the difference between North and South Korea — and remember that the North used to be the industrialized part.

(Note — if you flunked Geography, find Japan (if you can’t do that, skip this — you’re hopeless) then look due west. What looks like an island of light is South Korea — if you look closely you can see just enough points of light to realize that North Korea is actually there, but just barely.)

The always visible difference between capitalism and communism couldn’t be much more visible than that.
