Marxism: The New Trend?

I was reading an article today on ABC News about the renewed popularity of a book called The Communist Manifesto. It is becoming largely popular with the youth of Germany. The book was written by Karl Marx, the father of Communist thought. The publishing company in Germany that sells the book says it had been suffering in sales for many years, until now. The book started selling a few more copies annually in 2005, but in September of this year sales skyrocketed, selling more copies than they usually sell in an entire year. Hmmm...I wonder why the sudden revival of the famous/infamous commentary against capitalism is on the rise now? Just a thought.
