Not all industries prospered in the Boom in the 1920s of America.
Old industries such as Coal and Cotton did terribly in the Boom as people became interested in the new products such as clothes made from artificial material(polyester). Coal was an old source of power, in the 1920s oil and electricity became greatly used.
Agriculture was also poor many farmers left the farmland to find work in the city. As new people emerged, new demands also appeared. Instead of fresh fruits and vegetables, Americans preferred cereals and bread which lead to the decrease of demands in fruits.
In the 1920s, Argentina and Canada began to supply the world crops which lead to the drops of demands from USA directly.
