Did all Americans share in the boom?

The 1920's were generally a good time- women began to dress more freely, with lower hemlines (about to the knees at lowest)and the right to drink, smoke, and wear make-up. The 20's were also know as the "Roaring Twenties", and gave way to Jazz Music over classical music. It was only in the 30's that things became bad when the Great Depression struck. Most of the time in the Twneties were filled with dancing to the Charleston and flappers.
