What is Social liberalism?

Social liberalism also known as new liberalism in the United Kingdom, modern liberalism in the United States, left liberalism in Germany, and progressive liberalism in Spanish-speaking countries, is a political philosophy and variety of liberalism that endorses a social market economy and the expansion of civil and political rights. Under social liberalism, the common good is viewed as harmonious with the freedom of the individual, and social liberals overlap with social democrats in accepting economic intervention more than other liberals.
