What people were doing well economically during the 1920s?

During the 1920s, often referred to as the "Roaring Twenties," many Americans experienced significant economic prosperity, particularly those involved in industries like manufacturing, construction, and consumer goods. The rise of mass production and technological innovations led to increased employment and higher wages for workers. Additionally, the Stock Market boomed, allowing investors and affluent individuals to accumulate wealth rapidly. However, this prosperity was not evenly distributed, as many rural and lower-income groups did not benefit equally from the economic growth.
