I don’t think there is an imediate solution. Humams can not be trusted with power, it’s human nature. I see only 2 ways, either someone/thing else does it or, a more realistic one, technology becomes so powerful that we can manage the managers, monitoring their actions/choices (and voting?! maybe?!) Idk, but remember that tech is a sword and not a knife, if it monitors them.they would also monitor us.
Anyway there is no simple solution. Captalism as is today and comunism as is today are both bad options.
