This is a fascinating article in The Economist comparing Scottish independence to Yugoslavia pre 1990. The piece does not give any answers but rather raises questions and issues that are intriguing.
I particularly think the point near the end where the article says those in Yugoslavia were told everything would be the same but they would be richer is interesting. Anecdotally I have been told that, in Montenegro at least, people are now worse off then they were in a united Yugoslavia.
Personally, I speak with absolutely no political bias and am certainly uninformed but I would be very sad to see Scotland leave the UK as they make up a colourful and vital part of our culture and identity.
