I can't see a major financial event so much as a general dissatisfaction with the status quo for about half of the country for varied reasons.

 And while parallels and similarities are interesting to historians, they are most often just similarities.  
The KKK, for example, had three prime targets; Jews, Catholics and Negroes.  Here in Oregon, that played out against the Catholics; which is why we still have the anti-religious schools provision in our Constitution.   We retain that religious bigotry from our KKK legacy.

The antipathy to Jews and Catholics doesn't seem to have come over into the 'new' racist organization nationwide, however.
