Interesting post, and I started to look into Paul Krugman.
I do have some "strong opinions" but do not like to answer things "off the cuff".
I could not get to the rest of the questions without answering the first page, that bothers me, I would like to think the "entire drift" through !!!
So, I quit there. Suggest you copy/past and post the "entire list of questions" for thought.
Yes, I happen to think that the $147 crude price a couple of years back was "pure and simple Wall street greed" when they couldn't pay for those "big buildings" from ripping off the "mortgage market" any longer!!! But I do not want to answer things "off the cuff" either. So post the "whole story".
I would be interested in seeing what "Insider" thinks/comes up with on this subject. If you can get his "feed back" I think you will have something of value to "chew on" !!!
Will consider further comment.
