Wow.  Talk about gratuitous negativity.  Lots of people have a favorite theory about where Daesh came from.  Blame Bush.  Blame Obama.  Blame Islam.  Blame oil companies.  At least this hammer isn&#x27;t one we&#x27;re already sick of hearing.  What do you actually think is wrong with Piketty&#x27;s analysis, other than the fact that he has actually published on this topic before?
