As noted, the folks in the middle and lower middle are generally very stressed about inflation. It's obvious when their grocery bill goes up by a lot, and/or they have to stop buying hambuger and switch to hotdogs.
I once had to get by on a very limited income and those habits are still with me, I have to force myself at times to "splurge", but in Kroger, I'm looking for deals, and the day old meat section.
At least most folks are employed, it's something, if we hit a bad recession that UE figure could top 10% easily enough, and inflation might still be a problem (usually not).
Then tax receipts drop hard, the stock market drops hard, people feel poor so even those with some money and a job cut back and the whole thing spirals down.
