> Those aren’t fancy cuts or prime grade beef. Just regular steak... I don’t know how the low income families deal with a 30% increase in their grocery bills I don't think low income families are buying steak - and price increases in luxury goods can understandably grow faster than in staples like non-steak beef.
But _all_ cuts of beef went up by a lot as far as I can tell. So did chicken, fish, and all other sources of protein. It’s not just protein though, everything across the board is on average 25-30% more expensive now than it was 3-4 years ago. A cart of foodstuffs that used to cost $100 give or take is now $130-140. This isn’t some Whole Foods kind of situation, this is a run of the mill Kroger normal people shop at
So if it's actually 25-30%, that's a significant level of error but not an enormous one.
CPI says that, of those four years, almost all the inflation was in the middle two. So when it says 3.5% since last year, that's not a crazy number, it's more that it's hard to determine/remember which part of the inflation happened in exactly which month. Comparing today to 3-4 years ago is a better option for both accurate numbers and accurate memories.
