In 2020 I could get Mustang GT for $8k off MSRP. In 2023 Mustang GT MSRP is $42,495 and there is only $500 off.
To that I would say there is likely a problem with average. I didn't see a break down of the data in your link, but admittedly its my lunch break and I didn't have the time to really dig for it either. But its entirely possible that some groups saw an outsized growth in wages while others didn't.

You think the average income is being computed incorrectly? Or that there is just a lot of variance so many people are worse off? It is true that wage increases have been uneven, but they are actually much larger at the low end -- this is why you see the most inflation in low-wage service-heavy categories like restaurants.
The economic data indicates that average income has gone up more than prices have since the start of the pandemic. If you look at Real Personal Income (https://fred.stlouisfed.org/series/RPI) it's up 5% relative to the end of 2019.
And if you think inflation is way higher than is being adjusted for, you're simply wrong. The MSRP for a 2023 Mustang GT is $38,345 (https://www.kbb.com/ford/mustang/2023/). The 2020 was $38,320 (https://www.kbb.com/ford/mustang/2020/). The price of Chicken Breast is up 38%, not 100% (https://fred.stlouisfed.org/series/APU0000FF1101).
Yes, public opinion is irrational, but the more obvious political question is why public opinion is so wrong now, when often it is not so pessimistic about the economy.
