How did World War 1 affect the US?
The U.S. agriculture prospered during WWI. Since most of the
allies' economy was involved in the war effort, they turned to the
U.S. for food. However, after the war, the U.S. was still producing
crops at the same rate as it was during the war, and the Europeans
no longer needed to buy crops from the U.S. so overproduction
occurred so postwar U.S. agriculture was pretty bad.
