Leftism is a political ideology that emphasizes social equality, environmental protection, and government intervention in the economy. It advocates for policies that aim to reduce income inequality, support workers' rights, and provide universal access to healthcare and education. Leftist movements often focus on issues such as civil rights, gender equality, and climate change. Historically, leftism has been associated with various political movements and parties, including socialism, communism, and progressivism. Prominent figures in leftist thought include Karl Marx and Bernie Sanders. Leftism often contrasts with right-wing ideologies, which prioritize individualism and free-market principles.
