Political ideologies shape public policy debates as well as the social policy strategies developed to address social problems. The clashes among these long-standing political traditions—conservatism, liberalism, radicalism—reflect fundamental and often irreconcilable differences regarding social, economic, and political life. Ideology also shapes theories of racial and gender inequality. These ideological perspectives and theories are compared for their views on several core issues that underpin social welfare provision, including human nature, need, the general welfare, social problems, and the role of government. The resulting distinctions provide social workers with a framework to more effectively assess contemporary social welfare policies.
