The main cause of the economic growth in the 1920's was Henry Fords invention of the production line. this made once luxury items easy to produce and therefore cheaper and easier for the average person to buy. this also made many new jobs in new industries this was a cycle, more production and factories meant more jobs which meant more money and thus more people buying certain products which were hard to buy before the invention of the production line (this goes around).
