The problem with the US inflation debate is that it's heavily ideological. Many of the commentators who espouse the low inflation view are also in the "debt is free" and #MMT camps, i.e. have a vested interest in swatting down any possibility of underlying inflation pressure... pic.twitter.com/p76RJWWlNC

сюда напишу, чтобы вам обоим,
я не спец, и глубоко не копал,
но вот что дает даже поверхностный гугл

The Controversy
Originally, the CPI was determined by comparing the price of a fixed basket of goods and services spanning two different periods. In this case, the CPI was a cost of goods index (COGI). However, over time, the U.S. Congress embraced the view that the CPI should reflect changes in the cost to maintain a constant standard of living. Consequently, the CPI has evolved into a cost of living index (COLI).

я не говорю, что это не имеет смысла, но, как говорилось в анекдоте, "тут-то мне карта и поперла"

Over the years, the methodology used to calculate the CPI has undergone numerous revisions. According to the BLS, the changes removed biases that caused the CPI to overstate the inflation rate . The new methodology takes into account changes in the quality of goods and substitution. Substitution, the change in purchases by consumers in response to price changes, changes the relative weighting of the goods in the basket. The overall result tends to be a lower CPI . However, critics view the methodological changes and the switch from a COGI to a COLI as a purposeful manipulation that allows the U.S. government to report a lower CPI .

сами же говорят, что "новая методика показывает инфляцию ниже", хотя, конечно, сделано это было не для того, а только чтобы убрать "biases", просто, возможно, они искали только те biases которые повышают инфляцию
