Switching to Chained-CPI and How Politicians Spin it

I’m getting a bit annoyed at the liberal blogosphere about how they’re spinning the proposal to use chained-CPI for Social Security. Here’s Ezra Klein:

The way we measure inflation right now really does mismeasure inflation. Chained-CPI really is a bit more accurate. But that’s not why we’re considering moving to chained-CPI. If all we wanted to do was correct the technical problem, we could make the correction and then compensate the losers.

But no one ever considers that. The only reason we’re considering moving to chained-CPI because it saves money, and it saves money by cutting Social Security benefits and raising taxes, and it’s a much more regressive approach to cutting Social Security benefits and raising taxes than some of the other options on the table.

The question worth asking, then, is if we want to cut Social Security benefits, why are we talking about chained-CPI, rather than some other approach to cutting benefits that’s perhaps more equitable? The answer is that chained-CPI’s role in correcting inflation measurement error is helpful in distracting people from its role in cutting Social Security benefits. Politicians who are unwilling or unable to offer a persuasive political or policy rationale for cutting Social Security benefits are instead hiding behind a technocratic rationale. We’re not “cutting benefits,” we’re “correcting our inflation measure.”

Emphasis mine. I sympathize with Ezra’s annoyance here. Switching to chained-CPI is being billed as a “technical fix.” If we wanted to implement such a technical fix, we don’t need it to be part of a grand bargain. Social Security benefits should increase with inflation. If we’re using the wrong measure of inflation, then we need to fix that. The reason Republicans are so set on fixing it now is because their ultimate goal is to cut benefits, not to correct the inflation measure. Thus, Ezra’s right when he says:

We’re not “cutting benefits,” we’re “correcting our inflation measure.”

However, Ezra makes the exact same error in the bolded section above. Continue reading “Switching to Chained-CPI and How Politicians Spin it”
