Earlier quoted context omitted.
Swiss comp advantage started in WWII when they were used to exchange Nazis gold into other currencies - this gave them a topstart for the economic period after the war since they were perfectly connected globally and they understood to scale & keep this advantage for long time. Maybe its fading a little bit nowadays
This seems a highly biased view. You could also say that because Switzerland wasn’t war raged they had a had start.
The Nazis may have found the Swiss more useful as a 'neutral' country than they would have as conquered territory:
> No, the controversy in Swiss conduct comes from three major factors. The trade in gold, Nazi banking, and Jewish banking.*
> When the war began, Germany had less than 50 million dollars in gold in their national stores. Yet, during the war, the Allies claimed that the Swiss purchased over 300 million in gold from the Germans. Where did the extra gold come from? Well, the obvious answer is that Nazi Germany stole it from the countries they invaded. With most powers unwilling to accept what was obviously stolen gold as payment for goods, the Swiss didn't have the same scruples. They bought the gold for Swiss francs, which Germany than could use to purchase stuff they needed from other neutral powers such as Turkey. When confronted after the war, the Swiss only would admit to 58 million of French and Belgian gold, which they compensated the respective national banks for. Investigations couldn't prove the rest, and when suspiciously new, gold 20-Fr pieces began appearing in the late 1940s, bearing dates from the 1930s, no one seemed able to prove that the Swiss had melted down the gold and was trying to secretly pass it into circulation.
> Gold wasn't all they got though. The Allies also believed there to be hundreds of millions in assets from Nazi officials stashed in Swiss bank accounts. As the occupying powers of Germany, the Allies claimed that ownership of these accounts defaulted to them, while the Swiss not only disagreed, but also claimed near total ignorance, as their strict banking laws prevented any disclosure verifying the claims.

> The Swiss helped transform almost four-fifths of all German gold into highly convertible Swiss Francs. As a result, Germany was able to buy strategic raw materials from Spain and Portugal.
> Switzerland as a nation was immensely important to the German military machine and economic planning. In 1941, for example, Hitler received a billion Swiss francs as credit for the Russian campaign.
