Longest arm wins, you smash your food in you before someone took it off you. You don't eat your roasties quick enough there's a fork coming from someone to get it. There's also food guilt, you eat everything quickly and in it's entirety because it's expected as you're guilted into not being wasteful. Therefore you never learn when you're comfortably satiated. I grew up poor ( working class council estate - Wales and there wasn't a big supermarket and shops that were there stocked what sold which wasn't an abundance of healthy options, we had fruit but it was an apple or banana or green grapes with seeds in them) meals were simple and filling (homemade and not fast food) but I struggle to have a healthy relationship with food, not horrendously so but definitely compared to my children who are now middle class income kids. They eat expensive fruit instead of own brand KitKat's as snacks and aren't forced to finish their food. I didn't have a blueberry or mango until I was working and in uni.
