> Berlin isn’t the alpha economic city in Germany though. There isn’t really one, but it’s more like Frankfurt.
You are right. I will add one thing: Berlin is the alpha economic city in Germany for the new economy. Frankfurt is for finance, and Munich is for manufacturing, but those are the old economy -- barely changing.
Berlin has a lot of English speakers because it’s been a cool place for young people to move to from across Europe for the last few decades.
