@Slowmover - Maybe my posting was not too clear, I did put some thought into it but I was doing other things at the same time so maybe the wordage got mangled - Apologies if it did.
My question as quoted (to Frank as it goes) was about his comments relating to economic growth as opposed to PO as a specific issue. This has come up before and has descended into arguments. I am interested in what Frank says - I am happy if he PMs me instead of posting here if that helps.
As for PO - I have no idea, I am neutral. It may have happened, it may be happening, it may never happen. I have "heard" of Yergin, Smil & Roubini from books and articles I have read but I would struggle to tell you what they did or said - unless they were the back row for Manchester City in 1985 ?
As for "From whence have you come?" - I suspect a leading question too, but I'm happy to answer if you can expand on what you want to know ?
