Progressivism
A political tradition that favors using government to promote social reform, economic fairness and expert-led solutions to public problems.
Also called: Progressive movement, progressive politics
Progressivism is a reform tradition that holds society can and should be improved through active government, scientific expertise and social reform. As a historical movement, the Progressive Era (roughly 1890s to 1920s) produced antitrust law, food and drug regulation, the income tax, women's suffrage, the direct election of senators and many city and state reforms.
Progressive thinkers such as Herbert Croly and Woodrow Wilson argued that the Constitution's checks and balances were outdated and that an expert-run administrative state could serve the public interest better. Later, the New Deal and the Great Society carried the approach forward. Today the term is used by the left of the Democratic Party, which favors expanded social programs, stronger regulation, racial and gender equity measures and action on climate.
Conservatives often criticize progressivism for concentrating power in the federal government and in unelected experts, and for what they see as a rejection of limits found in the Founders' design and in natural rights. Progressives respond that markets and traditional institutions fail to protect people from exploitation, and that the Constitution must adapt, a view tied to living constitutionalism. The term overlaps with but differs from socialism and democratic-socialism.
