Why has the economy of Switzerland been one of the world's most stable economies historically?

Answer 2

Switzerland banks have un-named, "numbered accounts" where n**i, Mafia and other bad guys can store stollen wealth without having to pay taxes in their own country, because the money can't be traced.
