Exports from Germany to the nations it owed exceeded what could be produced by their economy, resulting in hyperinflation. Hence why they needed wheel barrows of money.

This is a historical fact that changed the west's views on war reparations and resulted in the conclusion that nation building was a requirement of post war efforts (for stabilities sake).

WW1 is regarded as a major cause of WW2. It wasn't a case of "The Great Depression happened then Germany decided to have a World War"... No, the poverty hit them particularly hard and whenever there's an external drain on manufacturing that outstrips the ability of a market to keep up, you always get hyperinflation.

Likewise there are other precedents for this in Zimbabwe's hyperinflation and Venezuelas:

So no, it's not "Nazi propaganda". It's why rebuilding after war is more prioritized, and why war reparations aren't as much anymore. We saw how that went in Germany.
