Not directly related, but I don't that model works anymore. Switzerland is landlocked and surrounded by the European Union that unlike the independent neighbors of the past applies pressure coherently. Over the years Switzerland seems more and more aligned with both EU and US and I don't think they have much of a choice.
They have a choice to a point but today, isolating is regressing; there's a lot of money to be made if you have healthy relationships with your neighbours.
That logic applied in WWII when Switzerland was surrounded by Axis powers and they nonetheless got excellent outcomes by officially remaining neutral. The model will probably keep working until someone invades them.
