Quote from MKTrader:
No, CPI manipulation started in the 70s and it's gone through other politically-expedient "revisions" since then. At this point, it's worthlesss. Dubious product substitutions, so-called "hedonics" (reducing price for supposed product quality or satisfaction), and owner's equivalent rent. Not to mention the asinine idea that we take out food & energy due to "volatility." Over the last 11 years, real CPI (which has enough problems, as noted above) has been higher than "core" over 80% of the time. The same was true in the 70s. The alleged volatility is all on the upside. How convenient.
MIT's Billion Prices Project shows real inflation in the 8% annualized range. John Williams of ShadowStats computes CPI the old way and he's had it over 10% for awhile. The bottom line: "core" CPI is a joke and deflation was about as much of a threat as an alien invasion. The Fed-as-heroes hogwash is just another sad chapter in comic book U.S. history. Soon enough, it will be in the textbooks along with the "we would've all gone under without bailouts and hundreds of billions in stimulus" drivel.
