Pearl Harbour helped America because it got rid of the depression it was going through since 1929. In 1929, the wall street crash led America into a depression. Unemployment was high and people were starving, Roosevelt had introduced the New Deal which was helping but joining in WW2, which they did because of Pearl Harbour (when Japan attacked America), is what brought the economy back up. This happened because people were conscripted into the army, and more people were needed to build weapons. This helped end unemployment, and thus helped end the depression.
