I think this NYT headline and article kind of captures what is happening....and what poster
Brett Wyman is picking up on. One study cited, from the 90s, is that "inflation, even at moderate levels, frustrated ordinary citizens so much more than economic theory implied it should". There's real pain for sure, especially, as you're implying for consumers who are more challenged economically. However there's a generalized outsized grumbling throughout the population, even in the higher tiers....where's there's a lot more slack...or give in their household budgets. And I think gas prices are where we see this grumbling more than anywhere in the economy. It's the price that pretty much everyone knows off the top of their heads.
