Nothing to do with evil foreigners or some other Jews are at fault conspiracy.

I wouldn't exclude those as causal agents, although foreigners are typically less 'evil', and more seeking the most advantageous situation for themselves. The small hatted group does seem to have had an inordinate level of participation in facilitating the gibs giveaway.

The bigger problems arrive when the systems become so detached from reality that general mistrust in them becomes the norm. That's when it becomes foolish to pay taxes to contribute to a fantasy, and the whole system begins to break down.
