Historically, satire has satisfied the popular need to debunk and ridicule the leading figures in politics, economy, religion and other prominent realms of power. Satire confronts public discourse and the collective imaginary, playing as a public opinion counterweight to power (be it political, economic, religious, symbolic, or otherwise), by challenging leaders and authorities. For instance, it forces administrations to clarify, amend or establish their policies. Satire's job is to expose problems and contradictions, and it's not obligated to solve them. Karl Kraus set in the history of satire a prominent example of a satirist role as confronting public discourse.
