I'll note that Steve Forbes supported Trump in 2016, and claimed last year that Joe Biden is "not up to the job anymore" - although this is not necessarily relevant.
We can't change how we look at inflation based on the perception we want to achieve. This is what we have measured since 1983. And what if the change the formula back? Then we have a new number. And now what?
The article claims that the previous formula correlates better with sentiment. Maybe so. Sure, ever increasing money supply might make you feel rich, when in fact you are not. Did we think we will never have to be pay the bill for over a decade of near-zero interest rates?
The current sentiment seems to be as much influenced by what people want to believe or what their peer group on social media believes.
