Where has all the money in the world gone?
It's been a long time since I read it, but the top reply on Reddit reminds me of Human Action http://en.wikipedia.org/wiki/Human_Action (the wiki synopsis doesn't remind me at all of the book I read) by Ludwig von Mises http://en.wikipedia.org/wiki/Ludwig_von_Mises. Once somewhat influential I think the book has fallen into obscurity. My memory is von Mises constructed a rational economic system using a bottom up approach starting with human action, rather like the the Reddit poster attempts.
