What does it have to do with they way they have to manage way higher population density? Singapore is 2/3 Swiss population on 1/3 of the Canton of Vaud.. They are 18 Chinese cities with a population over 10 million.

Good for them I guess?

Not everyone wants to live in a Chinese style mega city.

Fwiw I am a foreigner in Switzerland (I live in Zürich) and I can definitely understand why the people of Switzerland don’t want it more crowded.
