Social democracy is a political ideology that seeks to promote economic equality and social justice through a combination of state intervention and market mechanisms.

Social democracy proposes to achieve economic equality through a combination of progressive taxation, the redistribution of wealth, the nationalization of key industries, and the expansion of social welfare programs.

In a social democracy, the state plays a significant role in regulating the economy, providing social welfare programs, protecting the rights of workers, and promoting economic growth.

Social democracy is associated with a number of key policies, including universal healthcare, free education, affordable housing, and a strong social safety net.

Social democracy differs from other political ideologies in that it is more focused on economic equality, more supportive of government intervention in the economy, and more committed to social justice.

Social democracy faces a number of challenges in the 21st century, including the rise of globalization, the increasing inequality, and the decline of the labor movement.

Social democracy can be adapted to meet the challenges of the 21st century by embracing new technologies, promoting worker cooperatives, and supporting universal basic income.
