> Food, shelter and transportation aren't included in the CPI.
This is wrong. Food, shelter, and transportation are all included in the basket used to compute CPI. [0]
> The CPI represents all goods and services purchased for consumption by the reference population (U or W). BLS has classified all expenditure items into more than 200 categories, arranged into eight major groups (food and beverages, housing, apparel, transportation, medical care, recreation, education and communication, and other goods and services).
> 9. Is the CPI a cost-of-living index?
...
> Both the CPI and a cost-of-living index would reflect changes in the prices of goods and services, such as food and clothing that are directly purchased in the marketplace; but a complete cost-of-living index would go beyond this role to also take into account changes in other governmental or environmental factors that affect consumers' well-being. It is very difficult to determine the proper treatment of public goods, such as safety and education, and other broad concerns, such as health, water quality, and crime, that would constitute a complete cost-of-living framework. Since the CPI does not attempt to quantify all the factors that affect the cost-of-living, it is sometimes termed a conditional cost-of-living index.
Public services are being gutted in the US. I think this explains why cost of living indexes can be north of 10% while the CPI is < 2%.
It doesn’t explain how groceries, rent, medical care and education costs have all skyrocketed without raising the CPI. My guess is that people are spending less than they used to on things like recreation and apparel, due to lack of money.
I think he refers to the fact that those categories have their inflation higher than CPI.
CPI weights changed in 1980, and seemly when using old weights the CPI is 10% instead.
I've read (I didn't checked with all details, I don't live in US so it is not that relevant to me) that a major change is that the cost of having a shelter had its weights greatly reduced. (I don't mean the "housing" category in general)
I should have been more specific. Certain rents are included, but house prices are not. Gasoline and bus fairs are included, but the cost of buying a car is not. And, various food items are seasonally adjusted in a favorable manner.
Over time, the index has changed in a manner that grossly underestimates the inflation the average person experiences.
If you did include houses and cars, how would you account for their general improvement over the years? My grandpa used to get rid of his vehicles as the approached $50k miles. They were just too unreliable and costly repairs were right around the corner. Today even junky cars can make it to $150k. They use less fuel, they have better comfort, and they can just do more in general with tech inside them. So if the value the car provides goes up 4x but it's price goes up 2x, what is its contribution to inflation?
Your grandpa could buy a new car for $1500. More like price went up 20x. Incomes have not kept up with this even if you can argue that a new car today is 10x as "valuable" as one built in the 60's. And, the people making the call on those gray areas have an incentive to adjust reported inflation downward.
