Those kids that didn't grow up with cooked meals are very unlikely to cook for themselves or their own eventual children. They're going to stick to 90 second rice pouches, ramen packs, mac n cheese, "salad kits". I can tell you right now a Kraft Mac n cheese cup is cheaper than what I would spend on pasta & the cheeses to make a roux. Easier to prepare, too.
I don't see people in Walmart buying produce. If they wanted that they'd go to one of the Latino grocery stores or the farmer market. If they wanted pantry staples (flour, bread, eggs, milk) they generally go to Costco. Who goes to Walmart to buy anything fresh?
All I'm saying is just that buying the components separately would probably be cheaper and result in a healthier meal.
But yeah you're right about many people not liking to cook due to lack of time or other reasons.

Well they wouldn't sell if people didn't buy it. I do see your point of course.
