Germany was doing fine until the Wall Street Crash killed them. Nothing the Weimar Republic could have done would have prevented the mark from collapsing, unless the allies agreed to defer payment until the global crisis was over.

Nazism threw away the old economy and was still cap in hand begging to Chase Manhattan by 1937, and was already trying to buy resources on credit according to Shell Oil documents from 1936.

The Weimar Republic lasted 15 years and survived a financial crisis by the skin of their teeth, but Nazism couldn't survive 3 years of smooth sailing because their natalist spending was more out of control than Hungary's (who are also looking down the barrel of bankruptcy after a Hail Mary of importing Chinese EV battery factories failed.)
