A cup of coffee in Starbucks may cost $6. A cup of (a better) coffee in any cafe 2-3 CHF. Can of Coke is about the same if bought in a touristy place, but in a grocery shop it's a 2L bottle that will be that much.

It's not. Cost of luxurious living is extremely high. In Geneva, in Zurich, perhaps in Bern and Basel. But you drive 10 minutes out of these cities and you have people who earn 40K CHF and live safely and decently, while still working in Geneva, Zurich, Bern and Basel. Things do cost more than in other countries, on average, but then an average Swiss lives well enough not to ever need a Wallmart.
(edit) You can downvote me all you want. I lived in Switzerland for few years, so $6 can of Coke is the Swiss version of bears on Moscow's streets - it's a cute bullshit.
