I find both cities, cultivate a strong "The rest is peasants" vibe - but Hamburg is quite at the top with this. It seeps through the media made there ("Der Spiegel") and the authors writting in it. Its also part of the multi-culturality and openess that comes with having a harbour - which a landlocked city "naturally has a hard time developing". So whenever you goto hamburg from the south, you recieve a ton of subtle signs about the superiority of the city and the "elb-adel" (aristocrats) and its old history ("Wir waren Hanse, wat ward ihr? Bauernvolk für den Märchenkönig bis pleite!"). The harbour of hamburg is old and awesome by the way!

The only thing that really helped to covercome these century old - was ironically the Conscription for the Bundeswehr in the cold war, intentionally mixing recruits allover germany and binding groups of friends together. That is now absent for a while- but the Ruhrpott and hamburg have missmanaged germany for quite a while now - and it shows, as subtle cracks of doubt in the superiority surface.

Cumex and Wirecard showed that elite as the lame ducks without a plan they really are.

PS: This explicitly ignores the Neo-prussians of berlin and the insults they throw at everything outside in the "incest-villages" as they call the rest of germany.
