It's called being NOSTALGIC.
Notaligia is being sentimental about the past. Cherry picking certain things and not working in the other aspects of the same time.
Well if you're being nostolgic for the lower prices of yesteryear, why aren't you giving the same consideration to the lower wages of those same years?
I found an online inflation calculator and entered the salary I had at my first post college job in 1982.
Converting it to the last year I worked it equaled a little bit less than the wage I made at my last job.
When I compared it to 2019, the number was what I would have totally expected to make if I were still working full time.
Also, I don't get what you are spending $100 to $150 on groceries in a week. Although, actually, in your first post you never gave a time frame, only saying you spend $100 a grocery trip.
My husband and I are in the fortunate position of being able to buy pretty much anything we want food wise
I buy rib eye or new york strip steak, fresh shrimp, pork loin, pasture raised eggs, kerry gold butter, the best cheese, olives, salami, uncured bacon. Also plenty of avocados, freshly squeezed lemon juice at $5 a pint, soup from the hot soup bar at $8 a quart and already prepared foods from the chef area. Plus plenty of fresh vegetables.
I go shopping 2 or 3 times a week, as the market I use is right down the road and I'm always needing something. I doubt we spend more than around $110 to $120 for the two of us.
What in the world are you eating anyway?
