Why is the price of gold more relevant than the Consumer Price Index?
both are terrible measures, as a long-term measure gold isn't so bad, but for point-to-point comparisons (as is done in the parent post), gold goes through some crazy speculative bubbles. The CPI is dastardly manipulated figures. (hedonic adjustments, substitutions)
That's substantially different from the CPI-based value. I wasn't quite expecting that.
