Necessary Illusions by Noam Chomsky explores how media serves as a powerful tool for controlling public perception and maintaining elite power structures. Rather than informing the public, mainstream media often reinforces dominant political ideologies and suppresses dissent through subtle forms of censorship, framing, and selective reporting. Chomsky argues that true democracy requires vigilant skepticism and critical engagement with media narratives, urging readers to recognize and challenge the "necessary illusions" that shape societal beliefs and behaviors.
