The economic problems in Germany, Italy, and Russia after World War I were so critical that contributed to totalitarianism.
Germany was destructed during the war. The terms of the Versailles treaty ended up devastating the economy of Germany because France and Great Britain forced Germany to pay for war reparations. Then it came the years of the Weimar Republic that totally failed and opened the door to the arrival of the Nazi Party and the leadership of Adolph Hitler.
In the case of Russia, the war made the nation very poor, and internal revolts initiated during the war. The consequences of the war produced downturns in farming, transportation was severely affected, causing food shortages. Russia had to abandon the war to focus on its internal revolts.
Italy was a weak nation after the war. No economy, poor people on the brink of starvation, high inflation, deep debts, food shortages, and unemployment. These conditions also opened the door to the absolutist government of dictator Benito Mussolini.
