This was a literal attempt to phase out home cooking.
I'd wager most Americans no longer make their own jam, jelly, mayonnaise, salad dressing, pickles, or barbecue sauce. & that a significant percentage have never baked bread, cake, or cookies from scratch.
I am, in fact, very happy I can buy frozen waffles, ice cream, and salami. I'd rather not spend my time MAKING it.
Note how the narrator stresses how clean and efficient production is, how tasty the food is. And the idea you could eat chili Monday, ham Tuesday, and beef stew Wednesday!? WHAT LUXURY.
