Political ideologies shape social policies by influencing how governments address issues like health care, education, and welfare. Different ideologies, such as liberalism, conservatism, and socialism, provide frameworks for understanding the role of government in people's lives and the distribution of resources. For instance, a liberal ideology may advocate for expansive social programs, while conservatism emphasizes personal responsibility and limited government intervention. These ideological foundations guide policy decisions and reflect the values and priorities of the society they govern.
