Modern American liberalism is the dominant version of liberalism in the United States. It is characterized by social liberalism, and combines ideas of civil liberty and equality with support for social justice and a mixed economy. The term "modern liberalism" in this article refers only to the United States. In a global context, this philosophy is usually referred to as social liberalism.
The American modern liberal philosophy strongly endorses public spending on programs such as education, health care, and welfare. Important social issues today include addressing inequality, voting rights for minorities, reproductive and other women's rights, support for LGBT rights, and immigration reform.
Modern liberalism took shape during the twentieth century, with roots in Theodore Roosevelt's New Nationalism, Woodrow Wilson's New Freedom, Franklin D. Roosevelt's New Deal, Harry S. Truman's Fair Deal, John F. Kennedy's New Frontier, and Lyndon B. Johnson's Great Society. American liberals oppose conservatives on most issues, but not all. Modern liberalism is historically related to social liberalism and progressivism, though the current relationship between liberal and progressive viewpoints is debated.
