Earlier quoted context omitted.
I dont think that Switzerland is more expensive than say San Francisco... While it is true that is one of the most expensive European countries the cost of living is very close to the one in the bay area...
It is not much a matter of cost of living but rather cost of the Swiss Franc versus other currencies. Currently, the swiss Franc is very strong, therefore making any Swiss product expensive to the exterior. It can become a huge problem for an economy based on trading with neighbors.
A Swiss franc is traded at roughly 1.09 Euros, I would say significant, sure, but not a deal breaker in high-tech industries. If we were talking about commoditized products I would have to agree but in our industries this is just not the case.
