Well, ok ...
Switzerland is one of the most expensive countries world-wide. But one with the lowest tax rates, too. So if you earn $5k - $6k a month before taxes, you can live here without any problem.
Sure there are places in Zurich where you pay like $8 for a cup of coffee. But hey, noone told you to go there ... right? You can easily get a coffee for $4 (still expensive compared to other countries, i know.)
Living quality is really good in Switzerland. Thats why so many foreign star come here. And since the first of Jan. getting a living and work permission here is easier than it used to be. The gov just wants to make sure that you can live from your own income.
Regarding language: Almost everyone in Switzerland speaks English. So you wont have any problems with that.
(only one thing ... the burger prices are as high as nowhere in the world. $5.4 for a big mac is quite huge
)
