You are probably smarter than me, but dairy prices are different than many other food prices. It's not all about inflation per se. While increases in production costs can raise prices, there are also government subsidies involved as well, which can control prices. I just know that I have seen dairy prices fluctuate when inflation wasn't an issue. USDA can control some of that.
tl;dr -- skip this!
I'm not claiming to be smarter than anybody, for sure.

I do regret I proved that point by the way I dashed off the previous post and with retaining the distorting focus on the OP's comment about eggs. I just wrote a post focusing on the difficulties in reading news these days, but I think enough is enough: to the trash can with it.
Anyway, what I had in mind when I talked about food prices was that they are so fundamental and so within the
ordinary experience of most people that it's a place where cognitive dissonance seems to have been widely triggered. "My $3.25 cardboard tube of oatmeal is now six bucks! I don't care what the television says." Basically sticker-shock, which was what prof's original post was expressing.
I
think I understand you to be saying that a large increase in the money supply alone doesn't adequately explain all the different prices changes? At any rate, for sure, that shortages, government policies, production costs, etc., are price inputs. I can confidently agree.
But consider (this is my answer) that official inflation numbers don't take all of that into account. They just compare prices before and after, in principle.
Now they don't actually do that, since some of the ways that the numbers are manipulated include changing the products included in the consumer "basket," and also (I forget the official name of this) but in more recent years: assuming that people will "trade down" as a general practice with the result that the official numbers can reflect the supposition like people will replace beef protein with peanut butter protein when price go up. But without specific mention of the fact. I remember being astonished hearing that (with that particular example) praised on NPR one day about a decade ago as an innovation "giving consumers credit for being 'smart.'" Numbers can also be released with fanfare and then "corrected" "off-camera" some months later. And consider how big a distortion -- and divergence from the concerns of ordinary people -- occurs when the prices of houses or rent are excluded from inflation! Isn't that right? Professedly (I would
guess) as being too "specialized" and thus needing their own "expert" report. But distortion is gigantic.
But to repeat, the general principle is that inflation figures just measure the cost of the "basket" today vs the cost last month or last year, or 4 or 10 or 20 years ago. And
that ratio is
indifferent to whether the price went up due to subsidies or shortages or higher production costs or whatever else. Isn't that right?
It's not a measure of what
caused the prices to go up -- although that's what all the "news" wants to blame or praise or emphasize or explain away. But those manuevers are not the numbers.
I care much more about strategies for reading and deciphering news that
@screenthis responded about. Grocery sticker shock, as I said, is just a common way that people realize that the statistics and real life aren't matching up. But I'm not touching that.
