ER took the words out of my mouth
Economists, explain what happened? First they'd have to agree that anything happened at all...and that's unlikely.
Economics is a science which hasn't even a passing familiarity with the concept of precision, which fills the gaps in its absurdly simplified models with heaping helpings of subjectivity.
Having said that, some great ideas have come from economists. But if you get a bunch of really smart people and tell them to contemplate their feet, you'll also get some great ideas.
