Classical liberals (now often called libertarians) regard the state as the primary threat to individual freedom and advocate limiting its powers to those necessary to protect basic rights against interference by others. Modern liberals have held that freedom can also be threatened by private economic actors, such as businesses, that exploit workers or dominate governments, and they advocate state action, including economic regulation and provision of social services, to ameliorate conditions (e.g., extreme poverty) that may hamper the exercise of basic rights or undermine individual autonomy. Many also recognize broader rights such as the rights to adequate employment, health care, and education.
