I am not Swiss but I have lived here long enough to realise they don’t do that out of simple generosity.

They realise that desperate people do desperate things.

And this jeopardise things that the Swiss value like quietness, not having to worry about crime, etc.

In the end nobody is an island and if someone is desperate the whole society is impacted a bit by that single desperate… a lot of desperate people and the society is impacted a lot by it
