Answer: The Great Depression of 1929 devastated the U.S. economy. A third of all banks failed. 1 Unemployment rose to 25%, and homelessness increased. 2 Housing prices plummeted 67%, international trade collapsed by 65%, and deflation soared above 10%.
At the end of the war, millions of people were dead and millions more homeless, the European economy had collapsed, and much of the European industrial infrastructure had been destroyed. The Soviet Union, too, had been heavily affected.
One of the main reasons for this is in order to stop losing support for the war effort. As was seen in the espionage act and the sedition act, talking disloyally about the war effort was seen as treason and people would be punished for such things. This was because the government did not want the people to sabotage the effort and to prevent others from supporting the war effort.
You should object to such laws because they infringe on first amendment rights since they are limiting your freedom of speech. Thanks to supreme court action, such laws would not be passed today because they would be unconstitutional since people have the right to criticize their government in a democratic country.
