alt Hacker NewsI don't know, friend. I am not a moral absolutist.
There's nothing that makes my heart tremble like starting the propeller of a small GA airplane. On that moment I reconnect with my nine year old self. You may call me evil, vulgar, stupid, shallow, vicious even. I know what I feel inside. The rest of the world can disappear on that moment.
Sorry.
Not many people buy GA aeroplanes, so it's a sensible decision for those to receive a lower weighting than other consumer goods in a general purpose index like the CPI.
There is a divergence between the prices of goods the US produces and those that consumers purchase, as measured by the GDP IPD and CPI respectively, but that is not something that is appropriate to measure using one highly idiosyncratic good, nor even a basket of goods like "things I personally want to purchase", if one is wishing to produce numbers that others agree are reflective of the average experience of many.
