"A popular government, without popular information, or the means of acquiring it, is but a prologue to a farce or a tragedy; or perhaps both."- James Madison (Answer in 150 words)

I Germany under Hitler Hitler rose to power by enormous support of masses. However, later he turned authoritarian - restricting popular information reaching him- which ultimately led to his downfall in WWII. II USSR under Gorbachev Gorbachev, after years of suppression of people under the Communist regime, opened the Soviet economy, which ultimately leads to its disintegration.

Disconnect with people and its repercussions:- "Prologue to farce or tragedy" highlights that authoritarian, unaccountable govts leads to popular resentment which manifests itself in form of protests. eg. Oppression by Chinese govt in Xinjiang and Tibet has led to protest. Capitalism and Exploitation Marx had highlighted that popular governments driven by capitalist system exploit workers. In an environment, where the troubles of poor don't reach the powerful, it will eventually lead to a revolution.
