Because of progressivism, how was America different in 1920 from what it had been in 1900?

By 1920 the Volstead Act was a law. This law prohibited alcoholic beverages and was considered at the time to be a victory for Progressives. The law would ultimately fail due to public apathy and a lack of funding for enforcement. Women also gained the right to vote in 1920 with the Nineteenth Amendment. While some states allowed women to vote in 1900, by 1920 women could vote nationwide. Many of the trusts such as Standard Oil that had existed in 1900 were broken into smaller businesses by 1920. Thanks to the Food and Drug Act, consumer goods became safer during this period as well. Patent medicines were a thing of the past by 1920 as companies had to clearly list the ingredients on the labels. Many national parks were in existence in 1920 thanks to the efforts of Theodore Roosevelt's Progressive domestic agenda.
