Housing and gold, to be used when the timescale is more than a few years. CPI is fine if the timescale is under a few years, because that is not enough time for its sins to compound.

You posted an incorrect interpretation of the FRED real wages line. All I owe the discussion is an explanation of why I believe your interpretation was incorrect. Which I gave. The fact that I went above and beyond to provide and defend both a theoretical alternative and practical alternatives is a nice extra. Your complaints that the practical alternatives aren't simultaneously perfect and easy is praise by faint damnation. Perfect and easy aren't the ways of this world. No, they only have to be better than CPI on long timescales to be good alternatives -- but the CPI methodology places that bar very low and both gold and housing clear it easily.
