Because I was traveling, I actually read this book on my e-reader. This is a great introductory primer for young people that Varoufakis originally wrote in Greek to his own child, Xenia. He has a lively voice and it is a very fast read, with lots of pop culture references. I think the most useful discussion is his exploration of the difference between exchange value and experiential value, and his call for radical democratization of the economy.
