Modern liberalism developed from classical liberalism and includes principles like the welfare state, welfare capitalism, and human rights protections. It aims to protect people from poverty through safety nets. Supporters argue this allows people to work harder and take risks, increasing success. Critics argue safety nets reduce incentives to work hard and success depends only on self-interest and competition as in classical liberalism. The document discusses these perspectives based on three sources, with one supporting modern liberalism and two supporting classical liberalism prioritizing individuals over communities.
