Demand and supply. Most Americans concept of "value" is not quality, it's quantity. Being unable to otherwise judge a thing on its merits, they take the bigger one. Not the one that is healthier, or more nutrient-dense. This, IMO, stems from the industrialization of our food supply. America came of age in post-WWII industrialization. Our food industry originally "began" because it was scaling to cheaply meet the food and logistics needs of a massive war. So Baby boomers (and therefore subsequent generations) learned to buy shitty, processed food "For America". Buying a box of mac and cheese isn't like picking out the best vegetables. All things being equal, you just get the biggest one for the price.
