Why did Plato believe democracies were inferior political systems?

Plato believed that democracies were inferior because he thought they were volatile and prone to instability due to the fluctuating nature of public opinion. He also argued that democratic decision-making could be easily manipulated by demagogues who appealed to the emotions of the masses rather than reason. Plato favored a meritocratic form of government led by philosopher-kings as he believed they would make rational decisions for the benefit of the society as a whole.
