In his Republic, Plato restricts private property among the rulers (guardians) and warriors to ensure they remain dedicated exclusively to the interests of the entire community.12

Plato argued that the possession of private property would inevitably corrupt these leaders by encouraging selfishness and greed, which he viewed as passions that cause social disturbances. By mandating an austere, communal lifestyle—where they share not only material goods but also spouses and children—he intended to prevent the ruling class from prioritizing personal gain or family interests over the welfare of the state.3142

This arrangement ensures that the elite govern solely by reason, supported by a warrior class that is entirely obedient to them. While the working population is permitted to own private property, the ruling classes are expected to receive only the basic necessities of life, thereby maintaining their focus on their duty to promote social harmony and the good of the city.3456
