Education (not just for learning, but for signaling).
Everything else is inconsequential in my budget.
Ofc, focusing on just one thing is very convenient for people who want to tell a particular story. (inflation is so bad! look at housing! there's so much deflation! look at food and TVs!)
For my family, housing is easily the primary expenditure -- around 6,000 CAD while (food + vehicle) amount to less than 2,500 CAD monthly. For a similar family in the same area with on vehicle, I estimate that housing probably takes at least half of their expenditure.
If Eggs go up 0% and Rent goes up 50%, CPI indicates a “25% growth” which is stupid.
The CPI does have a problem with not updating the basket as frequently as it could, which means it doesn't catch substitution effects and tends to overstate inflation.
