Just bad metrics all round.
Averages are a terrible, terrible way of looking at this for many reasons.
The obvious one being if food and rent take 80% of your wage, and food and rent are inflated by 20% , it’s going to hurt a lot more than If food and rent take 20% of your wage.
That captures it nicely. Prepared to hitch a ride on popular issues, but equally bigoted come crunch time.
