The CPI has powerful political ramifications, and administrations of both parties have been tempted to change the basis for its calculation. Especially since 1980, the definition of CPI has been altered repeatedly, though economists disagree whether the index underestimates or overestimates the true rate of decline in purchasing power.[26][27]
Back to me…
Hell the CPI was changed in the 83 for the expressed purpose of removing home prices from the inflation index. In other words…housing is inflating, quick cover it up!
