Everything you just said was wrong.

First: Keynsian Socialism and the Petrodollar currency system are tied together. You end these elites, both of those collapse and the global economic order with it. That, with population loss, means rampant deflation when the fiat monetary system collapses.

Second: Fiat currency was invented by the French, not the jews.

Third: Fiat currency's popularity was from Progressivism and Leftism as a way of redistributing wealth. Not only is it not jewish, it's explicitly anti-Capitalist, and designed to agitate banks, and isolate out the private ones. The point is to stop "money hoarding".

Fourth: The National Bank of Germany Reichsbank had existed for decades when the Nazis came to power. They did not disband it, they used it even more aggressively than the Weimar Socialists did. The National Socialists used central banking because it's a key feature of Socialist control over the monetary system, and a key element in re-distributing wealth.

Fifth: The Reich Bank issued Fiat Currency in the form of the Reich Mark. Being Socialists, the NSDAP massively devalued the currency.

Sixth: The German economy did not succeed under the NSDAP. It recovered at the end of the Weimar era, when the government introduced the "Hunger Chancellor" who basically destroyed government spending, and allowed the market to correct over the course of several years. Once the economy recovered, the SDP (Social Democratic Party who ran Germany in the Weimar era) announced that they would basically re-introduce their Socialist policies again. This is what helped catapult the NSDAP to electoral power, because they claimed that they would spend the money more wisely, and achieve Socialist end states, but wouldn't make the SDP's mistakes.

Seventh: They made all of them and worse. Germany experienced all the inefficiencies of any Communist economy through central planning, and horribly damaged their own industrial capacity through state seizures of entire industries. As a result, Germany began having major food shortages and starvation as of 1941. Part of the reasoning for seizing the wealth of jews was because they believed "jewish hoarded gold" could sustain the economy that they had been imploding with government spending. In the end, inflation had gotten so out of control that the Wehrmacht was plundering everything they could get their hands on in Eastern Europe to reduce the effects of inflation. You don't feel the shock of price rises from printing money, if you kill off German consumers in the war and steal every door hinge in Greece.
