I have already provided the proof, Toddster. What's your proof that the Clinton/Greenspan revisions make the CPI/GDP more accurate? I think it's funny that you are so completely pollyanish on the economy that you are even willing to rely on Slick Willie's changes to the CPI/GDP.
"As former Labor Secretary Bob Reich explained in his memoirs, the Clinton administration had found in its public polling that if the government inflated economic reporting, enough people would believe it to swing a close election. Accordingly, whatever integrity had survived in the economic reporting system disappeared during the Clinton years. Unemployment was redefined to eliminate five million discouraged workers and to lower the unemployment rate; methodologies were changed to reduce poverty reporting, to reduce reported CPI inflation, to inflate reported GDP growth, among others."

Maybe the fact that 10 year Treasury rates are below what your goldbugs say the old CPI would be?
