This never happened to me or anyone I know growing up, I think it's just a Stockholm thing.
I'm thinking it comes from the trauma of their peasant days where the upper class ruled Sweden/Norway/Denmark/Germany/Dutch/England with iron fists and they learned to be grinches. This is a huge culture defect. There are people who have been in poorer conditions that invite guests to eat over.
They come from a very selfish and individual culture... to the point that they treat their own community children like this. Weird.
On another hand, it's entertaining seeing scandi's get defensive because they're not used to their group being attacked or shamed. They're used to being praised... lmao. As Somali's who get attacked everyday from every direction, they need to learn how to toughen up.
