General Discussion

..the weighting that goes into CPI has been considered questionable by economists, statisticians, and others expert in mathematical analysis for a few decades.
I'm one of them.
I think the number is more accurately presented as whatever BLS reports × 1.2..
For instance, I think housing costs are overweighted given the substantial number of mortgage payers for whom monthly costs are fixed, and for whom, in many cases, have property tax bills that are statutorily limited for year over year increases.
I think transportation is underweighted because the cost of new cars has gone by by roughly 2x the reported inflation rate for 40 years or so. Used car prices are even worse.
I could go on, but really worth it.
Unless inflation is VERY low, I think the official number is too low by a meaningful to the consumer degree.
I agree that BLS isn't fudging numbers. We don't agree that their numbers are beyond reproach.
