Could easily be true in some areas of the economy, because professionalism seems really strong there and core technology infrastructure is often ahead of surrounding areas. However, my experience of living and working there suggests that it is very much not true in the areas I encountered: businesses cling to tradition and people prefer everything to be managed (contracts should be given to the "right" people, rules…
Things are very much done according to a formula. If you're an enterprise looking for a Java developer, only a guy whose CV says "Java" will do. C# is some other planet. I think it's a Germanic thing, they expect very specific qualifications. I remember meeting a guy who had a degree as a food chemist. I asked him what jobs he was after, and he said ... food chemist.
There is a startup scene in Zurich though. The tax rate is low, and people seem to have enough savings to give it a go, at least some of the young ones. It's not a huge number of people, but the Swiss are going about it in their own way, with a number "technoparks" and such. It's somewhat cosmopolitan in its outlook; people compare themselves to other startups around the world. Reasonable pay for such small firms, too. Came across more than one 6 figure job.
Salaries are high, but stuff is expensive, too. Daycare for a kid, at a public nursery, is CHF30K a year (USD is in the ballpark of CHF). I've met a number of Swiss people who'd like to have more kids, but it's just a lot of money to pay. A quite ordinary family meal at a restaurant can be 100. Buying the food from a supermarket ain't cheap, either.
I sometimes wonder whether GDP measurement is problematic. Quality of life doesn't feel like it's all that different between various industrialized countries, but the figures suggest they are. If stuff is expensive, that makes GDP higher. So a guy eating a $1 potato is enjoying a lower quality of life than a guy who paid $2 for his. This has implications for wastage, particularly when it has to do with large organisations such as government. Burn more money, get higher GDP. Tax rate also has implications. There's probably more black market business going on in certain countries, which also contributes to general welfare. But of course that doesn't go into official accounts, or at least it's quite hard to guess how much it is. Low tax places like Switzerland are more likely to have more stuff going through official accounts.
