They were neutral but certain bankers and families in Switzerland did fund National socialism and German industry, which wasn't unfounded when Hitler and his economists decided to privatize banks for a rearmament program.

There is a lie today that Hitler was funded extensively by either the warburgs, Rotschilds, the latter a lie, and big industrialists. The problem is the funding was nowhere close to the opposition groups to NSDAP and the marxist groups. The internationalists detested Hitler and National Socialism. And it goes without saying that Hitler became who he was because of the Treaty of Versailles. If that hadn't been imposed Natioal Socialism would not have risen to such great heights.

In the Pool's book on Hitler's funding as well as a french banned book in America, it illistrates that NSDAP was largel funded by dues, and membership payments as well as by poor and middle class Germans.
