You're putting the cart before the horse.

The Swiss desire peace. In their history they've suffered from some stunning little civil wars. In order to obtain and retain peace, they have amongst other things decided on a policy of strict neutrality. They can in part uphold this because of their geopolitical position in Europe -- an almost perfect natural fortress. It is easy to defend and they can keep themselves in food and water more or less indefinitely.

As a consequence of neutrality and defensibility, their country has natural competitive advantages in banking. Complaining about the Swiss being good at banking is like complaining about the USA being good at farming. In both cases natural features and political history have pretty much made certain outcomes more or less inevitable.
