While the people working in the late 30s had it much better than in the early parts of the depression, 1/4 to 1/3 of the adult male work force did not have a steady job as of 12/7/41. What ended the depression was the war and the massive government spending on said war. Now what kept it away after the war is the subject of endless political and economical debates to this day. Although there was a fairly severe recession/depression in 46/47 as all those GIs came home with nothing to do until a lot of them decided that college was an option.
Go to a college where they have the photos on the wall of the graduating classes. In the KY Engineering college it was amazing to see the huge spike in the early 50s but the rates stay much higher than before the war after that due to folks just getting better educations than the previous generation.
