Id say you’re righty as far as “Northern Europe” being Scandinavia+Germany. The Uk but london specifically is actually a pretty decent example of a contemporary protodystopia (I live there). On one side you have Mayfair which is like Monaco with some of the richest people in the world living there(and often the most corrupt - Russians, Saudis, Chinese oligarchs, African dictator’s families) side by side with Tower Hamlets in East London where a substantial amount of children suffer from malnutrition.

Malnutrition! And Tower Hamlets is of course a 5 min walk to the very core of the City of London.
