Not "evidence" particularly, but a few points: For one thing, the CPI calculators assume that if the price of a brand-name food increases, the housewife will substitute generic. That's total BS.
Note that when housing and car prices started the rapid climb over the last 25 years, they were dropped from the CPI.
Other? My wife has a better memory than any computer when it comes to prices.
I hear unending bitching. I also notice price increases in a lot of stuff I buy, whether it's gun related items or car repair stuff.
Powder and primers and bullets are way up. Hydraulic oil is way up.
Motel costs and restaurant prices have jumped a good bit in the last two years. I'm talking 20 to 40 percent in some cases. This contributes to the cost of doing business, a good bit of which is passed on to the consumer. Same thing for diesel prices and delivery costs which are added on to the price of consumer items and to services.
With the higher appraised values on real property, ad valorem taxes are climbing rapidly.
None of the above are down in this mythical 2% or 3% range.
