I haven't had a chance to wade through this one, but Rolling Stone has a long article on how Goldman has had its fingers in every major bubble in recent history.
Felix Salmon, also reviewed the article and found much to agree with.
Finally, Felix gets a response from GS.
I have to say though that Mr Salmon's stock went down a bit with me after he referred to vegans as "bonkers".
Anyhow, good stuff if you've got some spare time to read it all.
