General Discussion

The German population was already suffering from the effects of a world wide depression and I ternal political violence because aimless, unemployed youth has a bad habit of turning into foot soldiers for greedy old men grasping for power during chaos.

Hitler "gave them stability" by getting rid of his opposition and giving them a common enemy to excuse his brand of corrupt excesses and ideology.
Just as any other tyrant who would in his position.

So long as the normative majority of productive people - especially the landowners, business folks and professionals - feel like they're not being targeted, they're willing to let their competition and other lesser people or minorities be targeted.

Basic rule of thumb - it takes a middle class to create a successful, lasting revolution. They're the ones with enough education and money to fund and build enough of a stable foundation for the rapid change to be sustained without creating a significant power vacuum.

That's why the best way for wealthy interests to destroy a country's political structure is economically; destroy the middle class, create a significant wealth gap, so those without become more desperate - and violent - to survive.
Convince those remaining with money and resources that it's all a zero sum game and no one is to be trusted, and you'll get a pretty good protection racket going on.
