Usually they will print away their currency then start a war internally or externally or both as a cover-up for what they did. While the blood flows they will re-organize another currency that will be presented to everyone who has enough sense to survive. This new currency and set of laws will be a bullshit trap ending in absolute disaster just like the previous one and the one before that but EVERYONE will love it, fall on their knees and suck the governments dick because it means the war will stop. Pretty much that is what happens always. It is a feature of humans.
