If you think there hasn’t been an example of an alternative system of putting people in charge of a government, then you’re simply ignorant. Here’s one example for you to chew on:

The driving force of change in Cuba’s system are local organizations. There’s the Committees for the Defense of the Revolution, which operate on a neighborhood level, major workplaces and townships also form coherent political blocs, and the people who arise as leaders of the system are just community and workplace leaders who were elected into the system. There are no political parties, no big donors, and no entrenched power structure that vets candidates - its the most a government has ever been made up of regular people, and it’s communists who set it up.
