Why is Rousseau a forebearer of communism and socialism?

Jean-Jacques Rousseau is considered a forebearer of communism and socialism due to his critiques of private property and social inequality. In his work "The Social Contract," he emphasized the idea of the collective will and the need for a society that prioritizes the common good over individual interests. Rousseau's belief in the inherent goodness of humans and the corrupting influence of society laid the philosophical groundwork for later socialist and communist thinkers who sought to create more egalitarian social structures. His advocacy for a social contract based on equality and democracy resonates with the core principles of both movements.
