The Progressive era and the progressive reforms were reforms that were directly linked to the moral of society, trying to control the interests of the population, especially of the middle classes.
The Prohibition was the main example of these reforms, which prohibited the manufacture, transportation, and sale of alcoholic beverages. The Progressives believed that alcoholic beverages were the main reason for many social problems such as family violence and political corruption, but The Prohibition brought many other troubles.
The Treaty's required reparations amplified the state of Europe's economy in Germany, causing hyperinflation. The French insisted on the Treaty being harsh out of fear of Germany instigating another war.
A flood of cheap British manufactured imports that sold cheaper than comparable American-made goods made the post-war economic slump worse. Finally, the high level of debt taken on by the states to fund the war effort added to the economic crisis by helping to fuel rapid inflation.
