Potsdam certainly is the place where the rich and famous live (Günter Jauch, Hasso Plattner just to name a few), they are shaping the city by donations and philanthropy to restore it’s historic glory.
Potsdam has almost exactly the same GDP per capita as Berlin (€45,378 vs. €45,074) and is ranked only 63rd highest GDP per capita of the 110 large-ish cities in Germany. I'm not convinced. ;-)
