I think it's interesting to compare Switzerland with the neighbouring countries (e.g. France and Germany). I don't know about other companies, but Google Zürich pays much more than Google Paris or Google Berlin/Munich.
I think it's likely that the difference in labour laws is a contributing factor. Switzerland has very little by way of worker protection, instead placing a significant emphasis on unemployment insurance (Arbeitslosenversicherung).
