We could make it so that each person, as equals, gets a secret vote to put people in charge of writing laws, managing the treasury, appointing judges and military personnel, etc. In order to stop people from gaining too much power or authority we would limit the growth of their personal assets via tax brackets which increase based on the amount they gain, and when we end up with surplus of funds from taxation we then use that money to provide to the needy and build public goods which enrich everyone’s lives.
