Large swaths of the US population have been deprived of food culture for several generations now. There are many exceptions of course - Latino family bbqs in Southern California, or Cajun crawfish boils, are examples of food culture that’s well and alive that I’ve experienced personally. But you also have many Americans for whom the act of procuring ingredients and cooking is something so distant that it’s essentially alien - it’s been replaced by fast food, gas station food (frozen pizza, box of Mac & cheese), food delivery, etc. I’ve lived places where you had to easily drive 50-100 miles to find a farmer’s market - something unthinkable in Europe.
Nowhere is this more visible than in schools. In French schools, it’s not uncommon for the people making the food to make seasonal/local recipes, eat it with the kids, maybe even involving them lightly in the process. In the US, school cafeterias often are serving what is essentially gas station food.
(a funny side effect of that is Americans traveling abroad get their mind blown by foreign gas station food - see for example the sempiternal meme of tourists having their mind blown by the very mediocre Japanese konbini sandwiches)
Many have written about this, Michael Pollan is probably the most famous one.
