Growing up parents only made major shopping trips once or twice a month. Chest freezer the size of a coffin and sometimes second fridge in every garage with the washing machine seemed like a normal thing in the neighborhoods I grew up in.
America wasn't a Nation of large food beasts our food consumption was a heck of a lot lower. Moms always watching their figures, Dads rather have a cocktail than an extra helping. Kids wanting to playing outside rather than eating at the table. People on welfare weren't fat or obese either.
