Your using “inflation adjusted” which imo does not work.
Let’s say something costs $10 and you earn $100 a day. Then inflation comes around and it’s now $13, but your wage is $110 now.
You can use the “inflation adjusted” values to argue that it’s always been $13 in today’s money. But it’s not longer 10% of your income.
Inflation adjusted values only work when wages also go up and down with the same rate, which is obviously not true and the crux of the issue.
