Yeah the supposed middle class glory days and boom years post WWII definitely spent more on food as a percentage.
One also has to consider we have more more bills to pay these days too compared to back then… cell phones and cellular plans aren’t cheap, internet, streaming subscriptions, etc.
Feels like most households have these relatively new monthly payments they don’t truly *need* that weren’t around even 30 years ago. But they are things we feel we can’t live without now (and allow us to post on here, ha) so when food increases it hits most middle class harder.
