I do think it highlights the current weakness with the CPI though. A lot of modern economics is aggregation of large data sets and condensing it into one refined point that is applied to everyone. It's the average consumer, the average purchasing of an average basket of goods.
So while what you bring up does have some merit, the averaging of everything among these stats does hide some problems. As an example, if all food more than doubled in price, it'd have a horrific impact on a lot of low and middle income individuals, but in the CPI, it'd still only end up being a moderate increase in inflation.
The Keynesian tendancy to aggregate everything leaves a lot of blind spots and only captures the world, at a glance. I can understand why they do it, and to some degree it is necessary, but constantly combing over things with a broad comb is going to give an inaccurate picture.
How would you calculate it?
As an example, if all food more than doubled in price, it'd have a horrific impact on a lot of low and middle income individuals, but in the CPI, it'd still only end up being a moderate increase in inflation.
The "average family" spends about eleven percent of their income on food. If the index is 100, and the price of food doubles, the index increases by eleven which yes, would indicate an eleven percent increase in the CPI, not 100%. To get 100% increase in the CPI, you need all prices to increase by an average 100% including food, housing, transportation, clothes, etc.
