This was not the case.
The reasoning was simple: during the runup to WWI, Germany had been spending about 7% of GDP on its military.
The Treaty provided for about 40 years of reparations at the rate of about 7% of 1910 GDP.
The goal was hardly dismantling Germany's industrial production, but diverting a portion of its products to the Allies.
German industrial production was back up to prewar levels by 1921.
Your claim of 50x is simply divorced from reality.
The original total reparations were 269mm gold marks and German GDP was about 85mm gold marks - three years worth of GDP, not 50 years.
The reparations were easily sustainable by Germany.
You have “forced” me to do some research this weekend..I’m fairly sure of my facts, but will verify and discuss with you later. If you can provide any links/sources to substantiate your statements, I’d appreciate it. Thanks
