Expenses across the board have skyrocketed in the past year. Try and read some stories about what people living in colder, rural areas in Northern Europe (Scotland, Scandinavia, etc.) have had to deal with and you would start to get an idea.
If your rent suddenly increased by 30%, and winter heating bill tripled since last year and food costs 25% more than a year ago, then a lot of people with normally sufficient income would be having financial issues.
While I wouldn't accuse you of showing "extreme privilege" for not noticing a $3 price increase... good on you for not needing to worry about that... I'm tempted to accuse you of it for thinking it's only the poor that would. That's a pretty glaring disconnect.
Do you not even look at your phone/credit card when you tap? Do you really just randomly pay things?
There were several years early in my childhood where macaroni and cheese was one of the main courses in family meals, because we didn't have much money. This was until my parents worked multiple jobs and promoted their way into respectable wealth - hearing my friend make that comment really stuck with me and I laugh whenever I'm reminded of it, like today.
Anyway, I agree with you totally. The OP comment doesn't seem like a normal thing for people to say and is rather tone deaf IMO. I could make ten times more than what I do now and would still notice yogurt being 80% more in our grocery. Luckily for me I don't have to budget when it comes to groceries, but I'm well aware of how much pain some people/families must be going through.
