Bill Moyers had on Professor William Black, he is the only economics professor so far who makes sense to me.
The issue of criminality, collusion and the "Big Club" (populated by a few white guys, "...and you and I ain't in it") is at last being talked about openly on mass media, albeit on PBS.
To the short list of those helping us understand EM08, put Gretchen Morgenson Michael Lewis, Matt Taibbi, and now add Black.
Not only does Black agree with me about the crucial role of the ratings agencies, but he goes to the heart of the roles of Obama's point men, Tim Geithner, and former Goldman honcho and now Treasury Secretary, Hank Paulson.
