Final answer:
Progressive presidents in the 1910s pursued reformist policies to regulate industry and improve social welfare, whereas 1920s presidents favored pro-business policies and less government intervention in the economy.
Step-by-step explanation:
A progressive president in the 1910s such as Theodore Roosevelt, William Howard Taft, or Woodrow Wilson, pursued reforms aimed at addressing the problems caused by industrialization and urbanization. They sought to make the government more responsive to the people, combat political corruption, regulate big businesses, pass social justice legislation, and improve the general welfare of the public. Progressives believed in a more active government role to promote efficiency and social justice.
In contrast, presidents in the 1920s, starting with Warren G. Harding, embraced a return to 'normalcy' after the upheavals of World War I which meant a retreat from the interventionist policies of the Progressive Era. Policies during this decade focused on pro-business stances, less regulation, and an overall conservative approach to governance. The era was characterized by a laissez-faire attitude towards the economy and a shift away from the sweeping social reforms of the previous decade.
