It’s weird how he manages to be so casual about things, giving zero context. - Hey Germany acquired massive public debt in 1943-1944 (throwing it out like it’s just a random time).
Germany did the inflation thing, which was apparently so extreme Germans don’t like inflation anymore. But it shrunk the debt to basically zero by 1950. Which I assume came at the cost of the population struggling massively. They did a similar thing apparently after WWI which also was terrible. Germans, feel free to chime in here, I don’t know anything about this.
