Joseph M. Schwartz, a professor of political science at Temple University, a national vice chair of Democratic Socialists of America (DSA), and author of Coalition Politics and the Fight for Socialism, talks about the reasons for the rapid growth of DSA to become the largest U.S. socialist organization in the U.S. since the 1940s. DSA has thrown itself into resistance to Republican rule of the federal government and 25 state governments - as well as challenging the Democratic pro-corporate establishment at the national, state, and local levels. Joseph explains that DSA function as "an independent, visible socialist presence in mass social movements...(promoting) “non-reformist” or “transformational” reforms—changes in public policy that constrain corporate power and that illustrate how economic democracy better serves people’s needs, such as Medicare for All and free public higher education."
