We had an IGA in the small town I grew up in. The fresh food options there were borderline Soviet. We went to a butcher to get our meat when we didn't have meat from hunting.
We got produce direct from growers, at various markets and from our garden. I would get strawberries once a year when they were plentiful enough to be affordable in a pallete from a local bulk market.
Baked goods were what you got from home, otherwise you could have generic branded spongelike bread loaf.
American supermarkets blow my mind. I can get strawberries, blackberries and blueberries year round. There is a butcher in the store selling fresh high quality meats. There is a bakery producing French roundloaves, donuts and cookies, most produced in the last 24-48 hours.
It's incredible. And yet, when I unload my cart of fresh produce, meats, cheeses and baked goods it doesn't look like the carts around mine. They are full of canned foods, frozen foods, boxed foods, etc. I'm not judging. You can't beat a frozen pizza for satisfaction/effort, especially when you weren't expecting to feed anyone. But I can never get over the variety in my local produce section.
When I see people share "fast" recipes on YouTube they involve jarred sauces, spaghettiOs and raisins. (Fuck raisins.) You can make a great meal fast with few ingredients. If you take the time to have brown sauce or demi glace on hand.
Even with the aid of the supermarket and all it can provide, good food takes time. And that requires sacrifice. One parent has to come home after 8 hours working and cook. The kids can't do extracurriculars every week of the night. If you want to enjoy food culture, both cars have to be in the driveway a couple nights a week. And IMO that's why class and America's work culture have a lot more to do with our poor food culture than our grocery stores.
