What effect did world war 2 have on the nations economy?
FDR called the US The Arsenal of Democracy. Manufacturing plants were at work twenty-four hours a day. Civilian industries were converted to making arms, munitions, tanks, airplanes, and ships. Virtually everyone who was not in the military had full-time job and worked overtime hours. Even movie theaters remained open around the clock in major cities to accommodate defense plant workers who worked the late shift. Except for shortages in rubber, gasoline, meat, sugar, and housing, the wartime economy boomed.
In the World War II era, "mobilizing the economy" helped numerous nations end the Depression's effects. For the United States, in particular, gearing up for war and then actually entering the war had a decisively positive economic effect, as many products were needed to gain victory, which led to many more people being employed, among other "boosts" to the American economy.
World War II did not have any serious effect on the Palestinian Economy per se. The effect came when numerous Jews chose to immigrate to Mandatory Palestine following the war because they decided that they would rather not return to the places where they were deported from and would receive only hatred and disgust. This influx of refugees helped the nascent Zionist community declare independence.
If you mean how did the World War 2 effect the economy the answer is simple: The US profited greatly. They no longer had unemployment and their economy stabilized after the long depression. The United Kingdom did not recover from the depression as well as the US did so the war economy helped their sluggish economy somewhat but it still took ten more years after the war to fully recover. The European countries were devastated…
World War II is actually what completely brought the United States out of the Great Depression. In the beginning of the war, similar to what we did in WWI, we sold weapons, ammunition, and other war materials to the Allies in Europe. This greatly helped out economy and brought us out of the Depression.
