conservative double standards

Schroedinger’s Price Index by Krugman

Apparently Republicans are trying, once again, to extract chain-linking of Social Security benefits as the price of some kind of deal. I have no idea whether this will go anywhere; my guess, or maybe just my hope, is that Obama the Grand Bargainer has vanished from the scene. 

But there’s a funny point I hadn’t thought of until Matt O’Brien pointed it out. The alleged justification for chain-linking is that the conventional consumer price index overstates true inflation; it might overall, but probably not for seniors. In any case, however, as Matt points out, the very same Republicans who claim that Social Security benefits should be cut because the CPI overstates true inflation also insist that the Fed must stop quantitative easing, despite the absence of any visible inflation threat, because the real inflation rate is much higher than the official statistics indicate. 

But Matt, I think, fails to grasp the subtlety of the GOP position here. He accuses them of not knowing what they’re talking about. But surely what’s really happening is that they have a quantum-mechanics view of the situation: the state of the world in which the CPI overstates inflation and the state in which it understates inflation coexist in a condition of superposition, and what happens when you collapse the wave function depends on the position of the observer — that is, whether he’s trying to slash Social Security or bash Ben Bernanke. 

Or, on the other hand, maybe they don’t know what they’re talking about.
