First, trust nothing from this administration.
Second, the CPI is a farce so laughable it is not to be taken seriously.
A box of granola bars use to have 6 bars, now 5.
Items that came in one pound bags now have 14 ounces.
Ice cream was 1/2 gallon.
Everything on the sorecshelves come in bigger boxes with less product while the CPI still counts it per box.
Real inflation since zero is at least 25% higher now than 2008.
Excellent point.
I suspect that the unit pricing history is available for all of those products and more in the computers of the retailers. Somebody should do a study of a typical grocery cart of items and show the unit price increase over the last 6 years.
