Did the republican era of the 1920's bring peace and prosperity to all Americans?

In my opinion, the republican era of the 1920s brought peace and prosperity to the majority of Americans.During this time period many factors contributed to this. One example was the Fiscal policy. The Fiscal policy lowered the prices on goods on services making it so much easier for many for Americans to afford more. From Henry Ford's mass production of cars made it possible for many people to afford cars by cutting to under $290 in 1926. While at the same time Ford doubled workers wages to $5 for every eight hours. In this case, the mass production led to the start of many new industries which included steel, hotels, restaurants, and gas stations. Leading to many more job opportunities. Also, during this time the U.s. did many things to prevent war or conflict with other nations by the Kellogg-Briand Pact. For every good thing, there is always a downfall. The surplus crops, the effect of the war debt left many farmers in poverty. Also, because of the fact that gasoline, natural gas, and electricity became a popular choice for energy, coal miners were often left with no jobs. All in all I have to say that the republican era of the 1920s brought peace and prosperity to the majority of Americans, but not everyone was satisfied.
