What should I ask Joe Stiglitz?

I will be having a Conversation with him, and please note this is the conversation I want to have, not the one you want me to have.  So what should I ask?  Note that Joe has a new book coming out The Road to Freedom: Economics and the Good Society.  That said, I also would like for the dialogue to cover Joe’s career more generally, starting with 1970 or so.

So what should I ask him?
