Heinberg made a generalized statement that anyone could have formulated, with historic antecedents to back it up too. Not exactly a stunning call. I recently noticed a comment of JM Greer's from 3 years ago predicting that investors would push the price of crude both too high on the upslope and too low on the backside; sound familiar? These aren't very complex formulations.
I haven't seen any published analysis suggesting that tight supply markets were the prime mover in dragging the economy down, outside of Jeff Rubin's. Don't think any of us are, either, pstarr's leaning heavier than most but who are these other Must Be Peak Oil people you're referring to? Sounds like a strawman. High commodity prices were a factor, to what extent remains to be seen. The 80-82 recession wasn't entirely due to Iran going offline, either, as some mistakenly state.
A poll about the effect of $147/bbl's effect on economies would be useful. Give at least 4 options, too, for nuance.
I've always been puzzled by people who fear that peak oil won't be recognized as the big factor in civilization's descent. It's like listening to people vehemently defend or attack a pro sports team, in fact, maybe it's directly analogous in some fashion. I've never understood the attraction there, either.
