Switzerland’s a major world financial center - much like New York City. I’d like to see a breakdown based on how close to strategic cities ...
There is only "one" - Zurich.
Other cities include Basel, Luzern, Zug and Geneva.
The first three of those can be reached in about an hour from Zurich - Geneva in three to four. There is a lot of commuting to and from these cities.
The last page shows a map - the majority of the cases are in the cantons bordering Italy / France.
