> Swiss world of rules makes the northern Germany feel as flexible as a South American country

That is quite unworldly. I worked on large projects both in Switzerland and in Germany. These are totally different cultures. The number of laws and the degree of bureaucracy in Germany is many times greater than in Switzerland (only surpassed by Italy). In Germany everything is forbidden that is not explicitly allowed, in Switzerland it is the other way round. In Switzerland everything can be negotiated; try negotiating with a German official. Good luck with that.

I have lived half of my life in Germany.

Let me guess, you were a child so don't really know what the bureaucracy is like there. Switzerland is actually much more progressive (good luck doingt anything online in Germany!!).

Quite easy, just use the Bürgerbüro online portal.

I lived in Geneva from 26 to 28 years old, as mentioned in other replies, come back to Switzerland every time I manage to, and have several good Swiss friends.

I also had to help a friend of mine newly moved into Baden in 2018 to settle in, so I know what bureaucracy she had to face until she was 100% done with everything and could carry on with her life having a proper bank account, address, mobile phone, internet, new car registration, the whole package.

On the other hand, when speaking to a government employee, you're mostly speaking to someone who can make an actual decision on that matter, and can help you to solve your problem. Yes, there are many rules, but living there I've never had the feeling that this made the country inflexible.

As south European, I think it is a personal matter, it basically boils down to how much one can adapt to living by rules, without the flexibility to bend the rules one is used to in other countries.

There are plus and minus to both approaches, the rules approach favours more the society overall as everyone gets the same, while the flexible approach kind of favours the individual.

Well, drive half an hour by car from southern Switzerland to Italy and you will notice that the road will be lined with garbage heaps on both sides. There are definitely some advantages if people are a bit tidy. And then try to achieve something at an Italian office without losing your mind. You can always negotiate with the Swiss, and there are always compromises.

See, that is a good example of culture shock, I have zero issues negotiating in Italy.

And as mentioned in other answers I enjoyed my time in Switzerland, and come back every time I manage to, so trying to make my point of view without attacking anyone.
