I'm curious, where did you find this chart?
The reason I ask is I went to the CPI Calculator at bls.gov. I entered in 93 cents (from your chart) for July, 1986. I calculated that worth for February, 2024 (most recent month available). The calculator returned $2.64, which is much less than the $4.20 shown on the chart. I didn't do all the fields as I have a lot of chores I need to finish today, but something just seems off there.
I would also argue that it's not that things are so expensive, it's that your money isn't worth anything. But that's a different conversation.
Calculator can be found here:

Oh, and for those economists saying "things aren't so bad..." Same government calculator. It requires $1.19 today to have the same worth as $1.00 in January, 2021. Good thing inflation is under control, right?
