Why were economists opposed to the terms of the treaty of versailles

They thought the world would suffer if Germany could not repay its huge debts.

Many economists felt that the reparations demanded from Germany were excessive and counterproductive. Operating from the principle of permanently weakening Germany, France was particularly keen on punishing Germany and limiting its ability to wage war. This approach, however, backfired because reparations were so severe Germany plunged into economic chaos. This situation allowed for the rise of Adolf Hitler and planted the seeds for WWII.
